How to Write a Refund Demand Letter for Overbilling and Hidden Fees in Service Contracts
When you sign up for a service at one price and suddenly find yourself being charged significantly more, it’s not just frustrating—it may be illegal. Whether you’re a small business owner dealing with an agency that raised its retainer without permission, a freelancer whose SaaS subscription quietly doubled in price, or a consumer facing mysterious “platform fees” that were never disclosed, you have legal options to demand your money back.
This comprehensive guide walks you through the process of writing an effective refund demand letter when a service provider has overbilled you or charged hidden fees. We’ll cover how to gather evidence, analyze your contract, understand the legal grounds for your demand, structure your letter for maximum impact, and know when to escalate. By the end, you’ll have a clear roadmap for recovering the money you’re owed and preventing future overbilling.
Understanding What Qualifies as Overbilling and Hidden Fees
Before you can effectively demand a refund, you need to understand what constitutes improper billing. Not every price increase is illegal, and not every unexpected fee violates your rights. The key is whether the charges align with what was actually agreed upon in your contract and whether the provider followed proper procedures for making changes.
Overbilling typically falls into several distinct patterns. The first and most common is the unilateral price increase. This happens when a service provider raises your monthly rate, hourly fee, or subscription price during your contract term without having the contractual right to do so. For example, you might sign a one-year contract for marketing services at three thousand dollars per month, only to receive an invoice three months later for thirty-five hundred dollars with no explanation beyond “updated pricing.” If your contract doesn’t include a clause allowing the provider to change prices at will, this is likely a breach of contract.
The second pattern involves unauthorized add-ons and service packages. These are charges for services or features you never explicitly agreed to purchase. You might see line items like “premium support,” “fraud protection,” “compliance package,” or “priority processing” appearing on your invoices without your knowledge or consent. Sometimes these charges are presented as “required” when they’re actually optional, or they’re automatically added without any opt-in process.
Drip pricing represents another deceptive practice. This is when a service provider advertises a low base price to attract customers, but the actual amount you’re charged includes numerous mandatory fees that only appear at checkout or on your first invoice. You might see a software subscription advertised at forty-nine dollars per month, but when you actually sign up or receive your bill, there are additional charges for “platform fees,” “transaction fees,” “administrative costs,” and “service charges” that bring your total to eighty dollars per month. California’s Senate Bill 478, which took effect in July 2024, specifically prohibits this kind of deceptive pricing in consumer transactions by requiring businesses to display the total price upfront, including all mandatory fees except taxes and reasonable shipping costs.
Automatic renewals with unexpected price increases create another category of billing problems. You might sign up for a twelve-month subscription at a certain price with the understanding that it will renew month-to-month afterward. Instead, when your term ends, you’re automatically enrolled in another twelve-month contract at a significantly higher price, often without clear advance notice. The Federal Trade Commission’s recently amended Negative Option Rule, which took effect in 2024, requires businesses to obtain express informed consent before charging consumers for subscription renewals and to provide a simple cancellation mechanism. Similarly, California’s Automatic Renewal Law requires conspicuous disclosure of auto-renewal terms, affirmative consent to recurring charges, and easy cancellation procedures.
Understanding which pattern or combination of patterns applies to your situation helps you identify the strongest legal arguments for your demand letter. The research and evidence you gather will need to demonstrate not just that you’re being charged more than you expected, but that the charges violate your contract or applicable consumer protection laws.
Gathering the Evidence You Need
The strength of your demand letter depends almost entirely on the quality of evidence you can present. Service providers counting on customers not keeping careful records, and many billing disputes fail because the customer can’t prove what was originally agreed upon. Creating a comprehensive evidence file before you write your letter gives you the leverage you need to succeed.
Start by collecting every contract and agreement related to your service relationship. This includes the master services agreement, any statements of work or order forms, renewal notices, amendments, and any updated terms of service the provider may have sent you. If you signed up through an online form, try to locate the confirmation email you received, as it often includes a summary of the terms you agreed to. Don’t assume that just because you clicked “I agree” without reading everything that you’re stuck with whatever the provider claims. The terms you actually agreed to are what matters, not what the provider wishes you had agreed to.
Next, gather all evidence of the original price representations. This is where many people fail because they didn’t think to save proof at the time of signup. If you still can access screenshots or PDFs of the sign-up page showing the advertised price, download them immediately. Check your email inbox for marketing messages from the provider that mentioned “no hidden fees,” “locked-in pricing,” or specific price guarantees. Look for your very first invoice or receipt, which shows what you were actually charged when the relationship began. If you shared information about the service with coworkers or business partners via email or Slack, those messages might contain useful contemporaneous evidence of what you understood the price to be.
Your invoices and billing statements form the core of your timeline. Start with your first invoice and go through each one chronologically, identifying exactly when the price changed or new fees first appeared. Create a simple spreadsheet or document that shows: Month 1 through Month 6 charged at X dollars, then Month 7 onward charged at X plus Y dollars in new fees. Calculate the total amount of overbilling by subtracting what you should have been charged from what you actually were charged for each affected billing period. This clear mathematical presentation makes it much harder for the provider to claim the overcharges are insignificant or that you’re misremembering the original terms.
Save all communications with the service provider about billing or pricing. This includes support tickets, chat transcripts, emails with your account manager, and any phone calls you took notes on. These communications often contain damaging admissions by the provider. For example, a support agent might tell you via chat that “yes, we changed our pricing structure last quarter” without being able to point to any contractual clause that gave them that right. Or you might find an email from an account rep saying “we’ll fix this on next month’s bill” which constitutes an acknowledgment that the current billing is wrong.
If you pay through a payment processor like Stripe, PayPal, or directly via credit card, gather your bank statements and processor records. These provide independent verification of what you’ve actually been charged and can be particularly powerful when the provider claims their records show something different than what you’re claiming. Payment processor data is also useful if you end up disputing charges with your bank or card issuer.
The single most valuable piece of evidence, if you have it, is a screenshot or archive of the original pricing page or signup form. In disputes over Stripe billing or SaaS subscriptions, cases often come down to whether the customer can prove what was displayed on the screen when they signed up. If you’re currently in a service relationship and haven’t saved this information yet, do it now before the provider changes their website. Use a tool like the Wayback Machine to see if archived versions of the pricing page exist from when you signed up.
Once you’ve gathered all this evidence, organize it chronologically and create a one-page summary timeline. This document should show: the date you started service, the original agreed price, the date billing changed, the new amount charged, the difference, and the total overcharge to date. This summary will form the backbone of your demand letter and makes it immediately clear to anyone reading it that you have a legitimate grievance backed by documentation.
Reading Your Contract Like a Billing Forensics Expert
Most people read their service contracts looking for what they’re getting. When you’re preparing to challenge overbilling, you need to read the contract looking for what the provider is allowed to charge and how they’re allowed to change those charges. This requires a different analytical approach focused on finding the precise language that either authorizes or prohibits what the provider did.
Start with the pricing and fee provisions. Look for the section that specifies your base price. Strong contracts say something concrete like “Client will pay three thousand dollars per month for the retainer services described in Schedule A.” Weak contracts say things like “Client will pay fees according to Provider’s then-current rate card” or “Pricing as quoted.” If your contract has specific numbers, you’re in a much better position than if it relies on external documents or future determinations. Pay particular attention to whether the contract mentions any additional fees beyond the base price. Does it say you’re responsible for “third-party platform charges” or “reasonable expenses”? These clauses are often where hidden fees hide.
The most critical provision to analyze is whether the contract gives the provider the right to change prices unilaterally. Look for language like “Provider may modify fees upon thirty days’ written notice” or “Pricing is subject to change at Provider’s discretion” or “Provider reserves the right to update fees by posting new rates to the website.” If you find language like this, you need to determine whether the provider actually followed the procedures their own contract requires. Did they give you thirty days’ notice before implementing the price increase? Did they post the new rates to the website in a way you could reasonably discover? Simply having the right to change prices doesn’t mean the provider can ignore their own procedural requirements.
If your contract doesn’t include any language allowing unilateral price changes, that’s powerful evidence in your favor. Under basic contract law, the parties’ obligations are set when the contract is signed. If the pricing terms are silent on modifications, the provider generally cannot change them without your agreement. A provider might argue that you implicitly agreed by continuing to pay the higher bills, but that argument often fails, especially if you complained or questioned the charges.
Automatic renewal provisions deserve close scrutiny. Find the section describing what happens at the end of your initial term. Does it say you automatically roll into month-to-month service? Another fixed term? Is there any language about pricing for the renewal period? For example, a contract might say “Upon completion of the initial twelve-month term, this agreement will automatically renew for successive twelve-month periods at Provider’s then-current rates.” That language might give the provider the right to increase pricing at renewal, but only at the renewal point, not in the middle of a term. Make sure you understand when your current term actually ends and whether any price increase occurred during a term versus at a renewal point.
For California consumers, compare your contract’s renewal terms against the requirements of California’s Automatic Renewal Law. The law requires that automatic renewal terms be disclosed in a clear and conspicuous manner, in visual proximity to the request for consent, and before the subscription agreement is fulfilled. If you’re a California consumer and your service provider failed to properly disclose automatic renewal terms or make cancellation reasonably simple, you may have grounds to challenge not just the price increase but the entire renewal itself.
Look for any clauses about add-on services or optional features. These provisions often say something like “Client may elect to purchase additional services as described in Provider’s catalog for the fees listed therein.” The key question is whether any services billed to you were truly “elected” by you through some affirmative action, or whether the provider added them without your opt-in. If the contract says add-ons are optional and require your election, but your invoices show charges for services you never asked for, that’s a clear breach.
Many modern service contracts include a provision incorporating the provider’s terms of service or website terms by reference. The contract might say something like “Client agrees to be bound by Provider’s Terms of Service as posted at website dot com.” This creates potential problems because the provider can argue that by updating their online terms, they’ve updated your contract. However, courts often scrutinize these provisions, particularly for material changes that impose significant new costs. A general incorporation clause typically doesn’t give the provider unlimited power to change fundamental economic terms like pricing. If the provider is relying on updated online terms to justify new charges, you should argue that material adverse economic changes require explicit new consent, not just silence or continued use of the service.
Dispute resolution and notice provisions tell you what procedural steps you need to follow before escalating to litigation or arbitration. Your contract might require written notice of any billing dispute within a certain timeframe, or it might give the provider a cure period to fix problems before you can take legal action. Make sure you follow these procedural requirements in your demand letter, both to preserve your legal rights and to demonstrate that you’re a sophisticated party who takes contractual obligations seriously.
Finally, look for any integration clause or entire agreement provision. This language typically says something like “This agreement constitutes the entire agreement between the parties and supersedes all prior negotiations, representations, and agreements.” An integration clause can work in your favor by limiting what the provider can claim you agreed to outside the four corners of the written contract. If the provider tries to justify charges based on verbal conversations or email exchanges that aren’t reflected in the contract, you can point to the integration clause and argue that those informal agreements aren’t enforceable.
Legal Grounds for Demanding a Refund
Understanding the legal theories that support your demand makes your letter significantly more credible and increases the likelihood that the provider’s legal counsel will recommend settling rather than fighting. You don’t need to write a legal treatise, but citing the specific laws that the provider appears to have violated shows that you’ve done your homework and that continuing to stonewall you carries legal risk.
The most straightforward legal claim is breach of contract. If your contract specifies a price and the provider charged more without contractual authority to do so, that’s a breach. Similarly, if your contract required certain procedures for price changes that the provider didn’t follow, that’s also a breach. Breach of contract claims are available in both business-to-business and business-to-consumer contexts. The damages you can recover typically include the amount you were overcharged plus potentially attorney’s fees if your contract includes a fee-shifting provision.
A related claim is breach of the implied covenant of good faith and fair dealing, which exists in every contract under California law. This covenant prevents parties from using discretionary contract language in ways that frustrate the other party’s reasonable expectations or that unfairly deprive them of the contract’s benefits. If your contract contains ambiguous language about fees or pricing that the provider is interpreting in an unreasonably one-sided way to impose unexpected charges, you can argue they’ve violated the covenant. For example, if a contract says fees will be “reasonable” and the provider suddenly doubles them, you can argue that no reasonable person would consider that good faith exercise of contractual discretion.
If your written contract is weak or there’s a dispute about what the contract actually says, you may have claims for unjust enrichment or money had and received. These equitable claims basically argue that even if there’s some ambiguity about the contractual relationship, it would be unjust to allow the provider to keep money they charged you under false pretenses or for services you didn’t agree to receive. These claims don’t require proving a contract breach, just that the provider received a benefit at your expense under circumstances where fairness requires them to return it.
For California consumers, several specific statutes provide powerful additional hooks. The California Consumers Legal Remedies Act prohibits specific unfair and misleading business practices in consumer transactions. The CLRA was recently amended by Senate Bill 478 to add a new prohibited practice related to hidden fees. The law now specifically prohibits advertising, displaying, or offering a price for goods or services that doesn’t include all mandatory fees other than taxes and reasonable shipping costs. If you’re a consumer who was quoted one price but charged a higher price due to mandatory fees that weren’t disclosed upfront, this gives you a strong statutory claim. CLRA violations allow you to recover actual damages, injunctive relief, and potentially attorney’s fees and costs.
California’s Unfair Competition Law prohibits unlawful, unfair, or fraudulent business practices. The UCL has an extremely broad scope and incorporates violations of other laws. If a provider violated the CLRA, the Automatic Renewal Law, or even just basic contract principles, that violation can also be pursued as a UCL claim. The UCL allows for injunctive relief and restitution of money that was unfairly obtained. While individual plaintiffs often prefer to pursue contract claims for actual damages, the UCL becomes particularly powerful in situations where many customers have been harmed by the same billing practices.
California’s Automatic Renewal Law imposes specific requirements on businesses that use automatic renewal or continuous service offers. The law requires that the automatic renewal terms be disclosed in a clear and conspicuous manner in visual proximity to the request for consent and before the consumer agrees. The business must obtain the consumer’s affirmative consent to the automatic renewal before charging them. And the business must provide a simple, easy mechanism for cancellation that can be performed online if the subscription was originally purchased online. Recent amendments to the ARL that took effect in July 2025 impose even stricter requirements, including provisions about cancellation that must be as easy as signup. If your subscription renewed at a higher price without proper disclosure or you’ve had difficulty canceling, the ARL gives you strong grounds to demand a refund of charges that were improperly obtained.
At the federal level, Section 5 of the Federal Trade Commission Act prohibits unfair or deceptive acts or practices in commerce. While private individuals cannot sue directly under the FTC Act, you can cite FTC enforcement actions and guidance in your demand letter to show that the provider’s practices mirror conduct the FTC has found unlawful. The FTC has been particularly active in recent years pursuing cases involving hidden fees, misleading automatic renewals, and difficult cancellation processes. For example, the FTC recently took action against Adobe for hiding early termination fees in its subscription terms and making cancellation unnecessarily difficult. The FTC also finalized a comprehensive rule on Unfair or Deceptive Fees that took effect in May 2025, requiring clear upfront disclosure of total prices and banning certain hidden fee practices in specific industries like event ticketing and short-term lodging.
The FTC’s amended Negative Option Rule, which covers free trials and automatic renewals, requires businesses to clearly disclose all material terms before obtaining consumer consent, obtain express informed consent before charging, and provide a simple cancellation mechanism that’s at least as easy as the signup process. Even though this is a federal rule, you can cite it in your demand letter to show that the provider’s practices fall below the federal standard for acceptable business conduct.
For payment processors and financial service providers, the Consumer Financial Protection Bureau has jurisdiction over unfair, deceptive, or abusive acts or practices. The CFPB has issued extensive guidance on junk fees in the financial services context, including overdraft fees, late fees, and various service charges. If your overbilling involves a bank, credit card issuer, payment processor, or other CFPB-regulated entity, you can cite CFPB enforcement actions and guidance to strengthen your position.
The key to effectively using these legal authorities in your demand letter is not to overwhelm the reader with citations but to identify the two or three that are most directly on point for your situation and cite them concisely. You want to demonstrate that you understand the law applies to your situation without sounding like you’re writing a law school essay.
Structuring Your Demand Letter for Maximum Impact
An effective refund demand letter accomplishes several objectives simultaneously. It clearly communicates what happened, establishes that you have documentation to back up your claims, demonstrates that the provider’s conduct violates your contract and potentially applicable law, makes a specific demand for resolution, and creates consequences if the provider refuses to resolve the matter. All of this needs to be done in a document that’s short enough that busy decision-makers will actually read it.
Start with a brief introductory paragraph that identifies who you are, what service you purchased, and the nature of the dispute. Something like: “I am writing regarding billing discrepancies on my account for your marketing services. I contracted with your company on March 15, 2024, for monthly retainer services at an agreed rate of three thousand dollars per month. Beginning in June 2024, I was charged thirty-five hundred dollars per month without authorization or explanation. This letter formally disputes these overcharges and demands a refund.”
The body of your letter should present a short factual narrative organized chronologically. Describe when the service relationship began and what price you agreed to pay. Reference specific documents that establish the original terms. Explain when you first noticed charges that exceeded the agreed amount and provide concrete examples from your invoices. Use exact dates and dollar amounts. Avoid emotional language or characterizations like “I feel scammed” or “this is highway robbery.” Stick to facts that can be verified by your documentation.
After establishing the facts, address the contractual and legal issues. Quote the specific provision from your contract that establishes the original pricing. If the contract is silent on price modifications, state that explicitly. If the contract requires specific procedures for price changes that weren’t followed, explain that. Then connect the facts to the legal violations. For example: “This price increase violates Section 3.1 of our Services Agreement, which fixes the monthly fee at three thousand dollars for the initial twelve-month term. The agreement contains no provision authorizing unilateral price increases. By charging more than the agreed amount, you have breached the contract.”
If you’re a California consumer, this is where you cite relevant consumer protection statutes. Keep it focused and specific rather than throwing in every law you can think of. For example: “These charges also appear to violate California’s Consumers Legal Remedies Act and Unfair Competition Law. The CLRA prohibits advertising prices that don’t include mandatory fees. California Civil Code Section 1770 subdivision (a)(29). Your pricing page advertised a forty-nine dollar per month subscription but my actual charges have consistently been seventy-nine dollars per month due to undisclosed platform fees.”
Make your demand clear and specific. State exactly how much you’re seeking in refund or credit, broken down by billing period if that helps clarify the math. For example: “I demand a full refund of the overcharges totaling two thousand five hundred dollars, calculated as five hundred dollars per month for the five months from June through October 2024. I also require written confirmation that future billing will be at the contracted rate of three thousand dollars per month.”
Include a reasonable deadline for response and specify how the provider should contact you. Two weeks is often appropriate for most commercial disputes, though you might give longer for complex situations or shorter for urgent matters. Provide your email, phone number, and mailing address so there’s no excuse for the provider to claim they couldn’t reach you.
The closing paragraph should strike a balance between being professional and making clear there will be consequences if the provider doesn’t resolve the matter. You might write something like: “I hope we can resolve this matter promptly without further action. However, if I do not receive a satisfactory response by the deadline, I will pursue all available remedies, including disputing the charges with my credit card issuer, filing complaints with relevant regulatory agencies, and pursuing claims in small claims court. I am preserving all rights and remedies under contract law and applicable consumer protection statutes.”
End with a professional closing like “Sincerely” followed by your name and date. If you’re sending this on behalf of a business, include your title.
Attach or reference your supporting documentation. You might write at the end: “Enclosed please find copies of: the original Services Agreement dated March 15, 2024; your pricing webpage as it appeared when I signed up; invoices from March through October 2024; and my calculations of overcharges.” You generally don’t need to include every email you’ve ever exchanged, but you should attach the key documents that prove your core factual claims.
Send the letter via email for speed and via certified mail return receipt requested for proof of delivery. The certified mail receipt proves the provider received your demand and cannot later claim they never got it. This can be important if you end up in litigation or arbitration and need to show you satisfied any contractual notice requirements.

Re: Demand for Refund of Unauthorized Charges – Account #[Your Account Number]
Dear [Provider Name or Sir/Madam]:
I am writing to formally dispute unauthorized charges on my account and demand an immediate refund. I contracted with [Provider Name] on [Date] for [describe service – e.g., “monthly marketing services,” “software subscription,” “professional services retainer”] at an agreed rate of [Original Price – e.g., “$1,500 per month,” “$49 per month,” “$150 per hour”]. Beginning on [Date of First Overcharge], I have been charged [Higher Amount] without authorization or proper notice.
On [Date of Original Agreement], I entered into a [written contract/online subscription agreement/services agreement] with your company for [brief description of services]. The agreement clearly established that I would pay [Original Price] for [description of what that price included]. I have attached a copy of [the signed agreement/the pricing webpage as it appeared when I subscribed/my initial invoice showing the agreed price] which confirms these terms.
The following timeline shows the unauthorized charges:
From [Start Date] through [End of Proper Billing Period]: Charged [Correct Amount] per [month/hour/transaction] as agreed.
Beginning [Date of First Overcharge]: Charged [Higher Amount] per [month/hour/transaction], an increase of [Dollar Amount or Percentage].
[If applicable: I first contacted your customer support about this issue on [Date] via [email/phone/chat]. I was told [brief summary of what they said]. Despite this communication, the overcharges have continued.]
I have reviewed the [Services Agreement/Terms of Service/Subscription Agreement] between us. Section [X.X] establishes that [quote the relevant pricing language from your contract]. [Choose one: “The agreement contains no provision authorizing you to change pricing during the contract term.” OR “While Section [Y.Y] allows pricing changes, it requires [describe the notice or procedure required], which you did not provide.”]
Your unauthorized charges constitute a breach of our contract. [If applicable: By charging fees that were not disclosed at the time of signup, you have also violated California Civil Code Section 1770, subdivision (a)(29), which prohibits advertising a price that fails to include all mandatory fees.] [If applicable: Your automatic renewal of my subscription at a higher price without proper advance disclosure violates California’s Automatic Renewal Law, Business and Professions Code Sections 17600 through 17606.]
I calculate the total overcharges as follows:
[Month/Billing Period 1]: Amount charged [$X] minus amount owed [$Y] = Overcharge of [$Z]
[Month/Billing Period 2]: Amount charged [$X] minus amount owed [$Y] = Overcharge of [$Z]
[Continue for each affected period]
Total Overcharges: [$XXX]
I demand the following resolution within fourteen days of your receipt of this letter:
- A full refund of [$XXX] representing all unauthorized charges from [Start Date] through [End Date], issued via [check/credit to my credit card/credit to my account/ACH to my bank account].
- Written confirmation that all future billing will be at the agreed rate of [Original Price] per [month/period/transaction], with no additional fees except [taxes/explicitly agreed charges].
- [If applicable: Removal of any negative marks on my account or credit reports related to disputed charges.]
Please respond by [Date – typically 14 days from date of letter] to confirm that you will honor this demand. You may reach me at [your email] or [your phone number]. I am also available to discuss a reasonable payment plan if an immediate lump sum refund presents cash flow difficulties for your company.
If I do not receive a satisfactory response by the deadline stated above, I will pursue all available remedies to recover the amounts owed. This may include:
- Disputing the charges with my credit card issuer under federal and state consumer protection laws;
- Filing complaints with the [California Attorney General’s Office/Federal Trade Commission/Consumer Financial Protection Bureau/relevant regulatory agencies];
- Pursuing claims in [small claims court/arbitration as required by our agreement/superior court]; and
- Seeking recovery of attorney’s fees and costs to the extent provided by contract or statute.
This letter serves as formal notice under [Section X of our Agreement/California Civil Code Section 1780/other relevant provision] and preserves all of my rights and remedies at law and in equity.
I have enclosed copies of the following supporting documents:
- [List key attachments: Services Agreement, pricing webpage, relevant invoices, etc.]
I hope we can resolve this matter promptly and maintain our business relationship. However, the overcharges must be corrected immediately.
Sincerely,
[Your Signature (if sending hard copy)]

What to Do If the Provider Refuses Your Demand
Even the most well-crafted demand letter sometimes meets with silence, denial, or an inadequate response. Having a clear escalation strategy in mind before you send your letter helps you respond decisively if the provider stonewalls you. The goal is to increase pressure systematically while preserving your legal options.
If you receive no response by your deadline, send a brief follow-up email or letter noting that your deadline has passed and that you are proceeding with next steps. Sometimes providers ignore initial demands hoping you’ll give up, but a follow-up showing you’re serious can prompt action. Give them a very short additional window, perhaps three to five business days, before escalating.
If you paid by credit card, one of your most powerful tools is the chargeback process. Contact your card issuer and formally dispute the charges. Under federal law and card network rules, you have the right to dispute charges for services not rendered as agreed or for billing errors. Your card issuer will typically put the charges on hold while they investigate, and the burden shifts to the merchant to prove the charges were legitimate. The detailed evidence file you assembled for your demand letter becomes crucial here. Provide your card issuer with your contract, the original pricing information, and the invoices showing overcharges. Keep in mind that chargebacks typically have time limits, often 60 to 120 days from when the charge appeared on your statement, so don’t wait too long to use this option.
For ACH or bank transfers, your dispute rights are more limited, but you can still contact your bank to report unauthorized charges. If the provider initiated transfers without proper authorization or in amounts exceeding your agreement, your bank may be able to reverse them or help you block future transfers.
Filing complaints with regulatory agencies creates a paper trail and can trigger investigations that pressure the provider to change their practices. The specific agencies depend on what type of service you’re dealing with and where you’re located, but several are particularly relevant for billing disputes.
For California consumers, the California Attorney General’s office accepts consumer complaints about businesses engaged in unfair or deceptive practices. Their online complaint portal allows you to describe the situation and upload supporting documents. While the AG’s office cannot act as your personal attorney, they do investigate patterns of misconduct and can bring enforcement actions against businesses that systematically violate consumer protection laws. Knowing that a complaint has been filed can sometimes motivate a provider’s legal department to resolve individual disputes to avoid further regulatory scrutiny.
The California Department of Financial Protection and Innovation handles complaints about financial service providers, including some payment processors and fintech companies. If your billing dispute involves a company that provides financial services in California, filing a DFPI complaint can be effective.
For services that involve federally regulated financial institutions or payment processors, the Consumer Financial Protection Bureau is the appropriate federal agency. The CFPB maintains a public complaint database and requires companies to respond to complaints within 15 days. Filing a CFPB complaint creates a permanent public record and can be particularly effective against larger companies that are sensitive to regulatory relations.
The Federal Trade Commission accepts consumer complaints about deceptive business practices, though they don’t resolve individual disputes. FTC complaints contribute to the agency’s understanding of market practices and can lead to broader enforcement actions. If you believe the provider’s billing practices are widespread and affect many customers, describing them in detail in an FTC complaint helps build the case for regulatory action.
If the service provider is a licensed professional or operates in a regulated industry, complaints to the relevant licensing board or industry regulator can be powerful. For example, contractors in California can be reported to the Contractors State License Board for billing disputes related to home improvement work. Medical service providers can be reported to the Medical Board of California. Real estate professionals can be reported to the Department of Real Estate. Professional licensing complaints can result in investigations, disciplinary action, and pressure on the provider to resolve disputes to protect their license.
Your contract likely contains a dispute resolution clause that specifies whether disputes must be resolved through arbitration, small claims court, or regular court proceedings. Read this provision carefully because it may limit your options. If arbitration is required, research the arbitration organization specified in your contract and initiate the arbitration process. Many arbitration clauses allow small claims court as an alternative, which can be faster and cheaper than arbitration for disputes under the small claims jurisdictional limit.
Small claims court is often an ideal forum for billing disputes involving amounts up to the jurisdictional limit, which in California is ten thousand dollars for individuals and five thousand dollars for businesses. Small claims procedures are designed for non-lawyers, filing fees are relatively low, and cases move quickly. The evidence-gathering and legal analysis you did for your demand letter translates directly into your small claims case. When you file, attach your demand letter and the provider’s inadequate response as exhibits to show you attempted to resolve the matter before involving the court.
If your case exceeds small claims limits or involves complex legal issues, you may need to consider hiring an attorney to pursue your claims in superior court or arbitration. Look for an attorney who has experience with contract disputes and consumer protection cases. Many consumer protection statutes, including the CLRA and UCL, allow prevailing plaintiffs to recover attorney’s fees, which can make it economically feasible for an attorney to take your case even if the disputed amount isn’t huge. Some attorneys will evaluate your case for free or for a modest consultation fee to determine whether it’s worth pursuing.
For disputes involving ongoing service relationships where you don’t want to burn bridges entirely, consider proposing mediation. Mediation is a voluntary process where a neutral third party helps you and the provider negotiate a resolution. It’s faster and cheaper than arbitration or litigation and often allows both parties to reach creative solutions that preserve the business relationship while correcting the billing problem.
Throughout the escalation process, continue documenting everything. Save copies of all complaints you file, responses you receive, and communications with the provider. This documentation becomes evidence if you ultimately end up in court or arbitration, and it also demonstrates to the provider that you’re serious and organized, which can make them more willing to settle.
How to Prevent Overbilling in Future Contracts
Once you’ve dealt with an overbilling situation, you’ll want to make sure you never face the same problem again. The best defense is negotiating protective contract language upfront and maintaining good documentation habits throughout the service relationship. Many of the contract terms that would have prevented your current dispute can be inserted into your next service agreement with minimal pushback from reputable providers.
The single most protective clause you can negotiate is a rate lock with an approval requirement. This provision states that the rates specified in the contract are fixed for the full term and that any rate changes, including pass-through fees, platform fees, or third-party charges, require your prior written approval before being implemented. A well-drafted version of this clause might read: “The rates specified in Schedule A are fixed for the initial term and any renewal terms. Provider may not increase rates, add new fees, or pass through any third-party charges without Client’s prior written approval. Any rate changes must be proposed in writing at least 60 days before the proposed effective date, and Client may decline such changes and terminate this agreement without penalty.”
For services that inherently involve variable pass-through costs, like payment processing fees or cloud hosting charges, insist that these fees be billed at cost with no markup. The contract should require the provider to provide documentation of actual third-party charges upon request and should cap any administrative fee for managing these pass-throughs. For example: “Provider may charge Client for actual third-party payment processing fees without markup. Provider may add a 5% administrative fee to other third-party charges. Provider will provide invoices or receipts from third parties within 5 business days of Client’s written request.”
Transparency and itemization clauses give you the information you need to catch billing problems early. Require detailed itemized invoices that break down all charges by category, including hours worked, expenses incurred, and any variable fees. For usage-based pricing, require access to usage data that explains how charges were calculated. A transparency clause might state: “Provider will deliver itemized invoices showing: base fees, variable usage charges with supporting usage data, expenses with receipts, and third-party charges. Client may request detailed breakdowns of any invoice line item, which Provider will provide within 7 business days.”
Automatic renewal provisions should always include advance notice requirements and clear cancellation rights. Rather than accepting a contract that silently rolls into a new term at whatever rate the provider decides, negotiate language that requires written notice of renewal and any price changes well in advance of the renewal date. For example: “This agreement will automatically renew for successive one-year terms unless either party provides written notice of non-renewal at least 60 days before the renewal date. If Provider proposes any rate increase for a renewal term, Provider must provide written notice at least 90 days before the renewal date. Client may decline the rate increase and terminate the agreement without penalty by providing written notice at least 30 days before the renewal date.”
For relationships governed by online terms of service, limit the provider’s ability to make material changes through silent updates to their website. Negotiate an amendment clause that requires your affirmative consent to material changes, particularly those affecting pricing, payment terms, liability, or intellectual property. The clause might read: “Provider may update its online Terms of Service from time to time. However, any changes that materially increase Client’s financial obligations, reduce Client’s rights, or materially change the services provided will not apply to Client unless Client provides express written consent to such changes. Provider will notify Client of any material changes at least 30 days before their proposed effective date.”
Include a billing dispute and cure provision that requires the provider to address disputes within a specific timeframe. This prevents situations where you raise a billing concern and the provider ignores it or promises to “fix it next month” indefinitely. For example: “If Client disputes any invoice in writing within 30 days of receipt, Provider will investigate and respond within 15 business days. During the dispute period, Client may withhold payment of the disputed amount without penalty. If the dispute is resolved in Client’s favor, Provider will credit Client’s account. If parties cannot resolve a billing dispute within 30 days, either party may invoke the dispute resolution procedures in Section X.”
For subscription-based services, insist on easy cancellation mechanisms that comply with the FTC’s Negative Option Rule and California’s Automatic Renewal Law. The contract should explicitly state that you can cancel at any time using a simple online form or email, with no requirement to call a phone number or endure a retention conversation. For example: “Client may cancel this subscription at any time by submitting a cancellation request through the online account portal or by sending an email to cancellations@provider.com. Cancellation will be effective at the end of the then-current billing period. Provider will not charge Client for any period after the effective cancellation date.”
Add a liquidated damages or penalty provision for improper billing. While these provisions require careful drafting to be enforceable, they can deter overbilling by making it expensive for the provider to charge you improperly. A simple version might state: “If Provider charges Client any amount not authorized by this agreement, Provider will refund the overcharge within 30 days of Client’s written notice and will pay Client an additional amount equal to 10% of the overcharge as liquidated damages, not as a penalty, representing the administrative costs and harm of dealing with improper charges.”
Beyond contract terms, develop strong documentation habits for all service relationships. When you sign up for any service, immediately save screenshots of the pricing page, confirmation emails, and your first invoice. Create a folder for each vendor relationship and maintain copies of the contract, all amendments, and billing correspondence. Set calendar reminders for renewal dates so you’re not caught off guard by automatic renewals. Review invoices when they arrive rather than letting them pile up unexamined, and question any charge that doesn’t match your understanding of the agreement.
For business relationships, assign someone on your team to be responsible for vendor invoice review. This person should have access to all vendor contracts and should know what you’re supposed to be paying each vendor. Implement a simple tracking spreadsheet that lists each vendor, the agreed monthly or variable rate, the contract term, and the renewal date. When invoices come in, they should be checked against this tracker before payment is processed.
Consider adding new vendors to a probationary period where you scrutinize their first few invoices very carefully. Many billing problems emerge within the first few months of a relationship, and catching them early is much easier than trying to recover a year’s worth of overcharges later.
Frequently Asked Questions
What if my contract says the provider can change rates at any time?
Even if your contract includes language allowing the provider to modify rates, there are limits to this discretion. First, check whether the contract requires any specific procedures for rate changes, such as advance written notice. If it does and the provider didn’t follow those procedures, they’ve breached the contract even though they had the underlying right to change rates. Second, under the implied covenant of good faith and fair dealing, discretionary contract provisions cannot be exercised in ways that are arbitrary, unfair, or designed to deprive the other party of the contract’s benefits. A rate change that’s massively disproportionate to market conditions or that occurs right before you’re about to launch a major project using the service could be challenged as a bad faith exercise of discretion. Third, for California consumers, even if the contract allows rate changes, the provider must still comply with consumer protection laws requiring clear disclosure of automatic renewals and pricing changes.
How long do I have to dispute overbilling charges?
The timeline depends on several factors including your payment method, your contract terms, and applicable statutes of limitations. For credit card disputes, you generally have 60 to 120 days from when a charge appears on your statement to dispute it with your card issuer. For ACH or bank transfers, you typically have 60 days from when you receive the statement showing the unauthorized charge to notify your bank. Your contract may require you to dispute invoices within a specific timeframe, often 30 to 90 days of receipt. Even if you miss these short deadlines, you can still pursue contract claims or statutory violations subject to longer statutes of limitations, which in California are typically two to four years depending on the type of claim. However, waiting too long weakens your case practically because memories fade and evidence disappears, so it’s best to act as soon as you discover overbilling.
Can I withhold payment while a billing dispute is pending?
This depends on your contract terms and the nature of the dispute. Some contracts explicitly give you the right to withhold disputed amounts while the dispute is being resolved. If your contract has such a provision, you can withhold payment without fear of default. If your contract is silent on this point, withholding payment carries some risk because the provider might claim you’re in breach. A safer approach is to pay the undisputed portion of the invoice while withholding only the specific charges you’re disputing, and to clearly notify the provider in writing that you’re withholding the disputed amount pending resolution. For credit card charges, you have the right to withhold payment on disputed charges while your card issuer investigates, and your creditor cannot report the amounts as delinquent during this period.
What if the overbilling is relatively small, like an extra hundred dollars?
Even small overbilling matters, both as a matter of principle and because small improper charges often continue month after month, accumulating into significant amounts. A hundred dollar overcharge each month for a year totals twelve hundred dollars. More importantly, letting small overbilling slide signals to the provider that you don’t carefully review invoices, which may encourage them to add more charges. Send a demand letter even for small amounts. You don’t need to threaten immediate litigation over a hundred dollars, but you should firmly state that the charge is improper and demand correction going forward and credit for past overcharges. Small claims court is specifically designed for these kinds of disputes, and many small claims jurisdictions allow claims under five hundred or one thousand dollars to be filed with minimal fees.
Should I continue paying for the service while disputing overbilling?
If you want to continue receiving the service, you should generally continue paying the base amount that you know is properly owed while disputing the overcharges. If you stop paying entirely, the provider may terminate your service for non-payment, and you could lose access to important tools or data. Pay the amount that matches your original contract and clearly document in your payment reference or accompanying email that you’re paying the contractually agreed amount while disputing the excess charges. This demonstrates good faith on your part and preserves the service relationship while you work toward resolution. If the overbilling has made the service too expensive to continue, you may prefer to cancel the service and dispute all improper past charges, but make sure you understand your cancellation rights and any early termination fees first.
What if I never signed a written contract and everything was agreed to verbally or via email?
Verbal agreements and agreements documented through email exchanges are still contracts, though they can be harder to prove. Gather all emails that discuss pricing, services to be provided, and terms of the relationship. If you received any written quotes, proposals, or invoices that show the agreed pricing, those are evidence of the contract terms. Under the statute of frauds, some types of contracts must be in writing to be enforceable, but most service contracts that can be performed within one year do not require a written agreement. The challenge with verbal or email-based agreements is that each party may have different recollections of what was agreed, so your evidence needs to be very clear. If the provider has been billing you consistently at a certain rate for months and then suddenly increases the rate without discussion, that pattern of dealing itself is evidence that the original rate was the agreed rate.
Can the provider terminate my service if I dispute their charges?
Whether a provider can terminate service during a billing dispute depends on your contract terms and the nature of the dispute. If your contract requires a notice and cure period before termination, the provider must follow those procedures even if they believe you owe money. If you’re paying the undisputed portion of charges and only withholding amounts that are genuinely in dispute, many courts would find that a termination for non-payment is wrongful. However, providers do sometimes take the aggressive stance of terminating service when customers push back on charges. If you’re concerned about losing access to critical services or data, consider whether you should download important data before sending a demand letter, or whether you should wait until after a project milestone to raise the dispute. From a legal standpoint, terminating service specifically because a customer exercised legal rights to dispute improper charges could itself be grounds for a claim, but that doesn’t help you if you need the service right now.
What if the provider claims they sent me notice of the price increase but I never received it?
This is a common dispute. If your contract requires written notice of price changes, the burden is typically on the provider to prove they sent proper notice. Merely showing that they updated their website or sent an email to an old email address may not be sufficient. Look at your contract to see exactly what type of notice is required. Does it specify certified mail, email to a specific address, or some other method? If the provider was supposed to send notice to your email on file but you’ve changed email addresses and never updated your account, that might weaken your position, though the provider still has some obligation to use reasonable efforts to reach you. If the contract says notice is effective when sent rather than when received, proving you never got the email is less important. Check your spam folder and old email accounts to make absolutely sure you didn’t receive anything, because finding that email undermines your credibility on other points.
How do I handle a situation where the provider offers a partial refund or credit but I want a full refund?
A partial refund offer is a negotiating position. The provider is acknowledging that some amount of the charges was improper while trying to minimize their financial exposure. You need to decide whether the offered amount is acceptable given the time, effort, and risk of pushing for more. Consider the strength of your evidence and legal position. If your documentation is ironclad and the contract clearly supports your position, you may want to reject the partial offer and continue pushing for full recovery. If there’s some ambiguity in the contract or your evidence has gaps, accepting a substantial partial refund may be wiser than risking small claims court. You can respond by thanking them for acknowledging the billing error and explaining why you believe the full amount should be refunded based on specific contract language or legal requirements. Sometimes a middle ground can be reached, especially if you’re willing to continue the service relationship at the proper rate going forward.
What if I’m a business and the charges are on a business credit card?
Business credit cards have fewer consumer protection regulations than personal cards. While you can still dispute charges, the card network rules for business cards are somewhat less favorable to cardholders than consumer card rules. However, you still have contract law remedies available. Your demand letter should emphasize the business relationship nature of the dispute and focus on breach of contract rather than consumer protection statutes that may not apply to business-to-business transactions. You can still cite relevant FTC rules and California’s UCL, which covers business practices affecting businesses as well as consumers. The practical leverage may be different because business reputation matters more in B2B relationships, so threatening to publicize the overbilling to industry peers or through business review sites can sometimes be effective.
Should I hire a lawyer to write the demand letter?
For straightforward overbilling situations with good documentation and clear contract terms, you can usually write an effective demand letter yourself using the template and guidance in this article. The cost of hiring an attorney to write a demand letter typically ranges from a few hundred to over a thousand dollars, which may not be economical if the disputed amount is relatively small. However, if your case involves substantial amounts, complex legal issues, or a particularly sophisticated or aggressive provider, having an attorney write the letter can be worth the investment. An attorney’s letterhead signals that you’re serious and may have better bargaining power going forward. Some attorneys will write a demand letter for a flat fee and agree that if the dispute escalates further, you can hire them for continued representation. Consumer protection firms sometimes offer free case evaluations to determine whether your situation justifies attorney involvement.
What happens if the provider’s business closes or goes bankrupt during the dispute?
If the provider ceases operations or files for bankruptcy protection, recovering your money becomes much more difficult. In a bankruptcy, you would be an unsecured creditor competing with many others for a share of limited assets. File a proof of claim in the bankruptcy proceeding by the deadline specified in the bankruptcy notice to preserve your right to any distribution. If the business simply closes without formal bankruptcy, you may be able to pursue the business owners personally if they personally guaranteed the service contract or if you can pierce the corporate veil based on inadequate capitalization or intermingling of personal and business assets, but these are difficult legal claims requiring attorney assistance. This is one reason why addressing billing disputes promptly while the provider is still operating is important. Waiting until accumulated overcharges become substantial gives the provider more time to potentially become insolvent.
Can I post about the overbilling on social media or review sites?
You have First Amendment rights to share truthful information about your experiences with a business. However, you should be careful to state facts rather than opinions that could be construed as defamatory, and you should avoid making false statements even if you genuinely believe them to be true. Saying “Provider X charged me $500 more than my contract specified and has refused to refund the overcharge” is a statement of fact that you can support with documentation. Saying “Provider X is running a scam” or “Provider X is stealing from customers” is a conclusory opinion that could get you into legal trouble if the provider decides to sue for defamation. Many businesses are very sensitive to negative online reviews and may be more motivated to resolve your dispute quietly if they know you’re considering posting publicly. However, some service contracts contain clauses prohibiting negative reviews or requiring disputes to be confidential, so check your contract before posting. These non-disparagement clauses are often unenforceable under federal law or state consumer protection laws, but you should be aware they exist.
What if the hidden fees are disclosed somewhere in fine print in the terms of service?
Even if fees are technically disclosed somewhere in lengthy terms of service, they may still violate consumer protection laws if they’re not disclosed clearly and conspicuously. California’s SB 478 requires that the advertised price include all mandatory fees, not just that the fees be mentioned somewhere in fine print. Similarly, the FTC’s guidance on deceptive practices makes clear that important information buried in fine print or lengthy legal documents may not be adequate disclosure if reasonable consumers wouldn’t find it. Courts apply a standard of what a reasonable consumer reading the materials would understand, not whether somewhere in hundreds of pages of terms there’s a sentence mentioning the fees. If you were shown a price of $49 per month in large font and only somewhere in paragraph 47 of the terms of service does it mention additional platform fees of $20 per month, that’s likely inadequate disclosure even though it was technically mentioned.
How do automatic renewal laws affect my dispute?
California’s Automatic Renewal Law and similar laws in other states impose specific requirements on businesses that automatically renew subscriptions. The key requirements are that the automatic renewal terms must be disclosed clearly and conspicuously before you agree to the subscription, you must give affirmative consent to the automatic renewal, the business must provide acknowledgment of your consent that includes the cancellation policy, and you must be given a simple mechanism to cancel that’s at least as easy as signing up. If the subscription renewed at a higher price than originally disclosed, or if you were never properly informed about automatic renewal, or if you’ve had difficulty canceling, you can cite ARL violations in your demand letter. Recent amendments to the ARL that took effect in 2025 make the requirements even stricter, including provisions about cancellation flows that cannot include unnecessary obstacles. Violations of the ARL can support claims under the CLRA and UCL and can provide a basis for demanding refunds of renewal charges.
Should I threaten to sue in my demand letter?
Opinions vary on this strategy. Some lawyers believe that threatening litigation makes providers take you more seriously and motivates them to settle. Others believe that threatening litigation causes the provider to immediately refer your matter to their legal department, which may be less flexible and more adversarial than their billing department would be. A middle approach is to state factually that if the matter is not resolved, you will pursue all available remedies, which may include arbitration, small claims court, or formal litigation, without specifically threatening to sue. You can also mention that you’re preserving all rights under contract law and applicable consumer protection statutes. This language puts them on notice that you understand your legal options without sounding like you’re trying to intimidate them. Save the more explicit threats for a second letter if your first demand is completely ignored.
What if the service provider is based in another country?
International billing disputes add complexity because of jurisdictional issues and difficulties in enforcement. However, if the provider does business in the United States or accepted payment through a US-based payment processor, you still have options. Your contract likely specifies which country’s laws apply and where disputes must be resolved. If the contract doesn’t specify, courts will look at factors like where the contract was formed, where services were performed, and where the parties are located. You can still file complaints with US regulatory agencies like the FTC and CFPB. Your credit card or payment processor dispute rights still apply even if the merchant is overseas. If you need to sue, you may be able to bring the case in your local court depending on the provider’s contacts with your jurisdiction, though enforcing a judgment against a foreign entity can be difficult. Consider whether the disputed amount justifies the extra complexity of international disputes.
Can I recover attorney fees if I have to sue?
Whether you can recover attorney fees depends on your contract and applicable law. Many commercial contracts include attorney fee provisions that allow the prevailing party to recover their fees. California has a reciprocal attorney fees statute that makes attorney fee provisions mutual, so even if the contract says only the provider can recover fees, you can too if you prevail. Several consumer protection statutes also provide for attorney fee recovery, including the CLRA and certain provisions of the UCL. This makes it economically feasible for attorneys to take consumer cases even when the individual damages aren’t enormous. If your contract doesn’t have a fee provision and no statute provides for fees, each party typically bears their own attorney fees under the American Rule. However, the possibility of having to pay your attorney fees if they lose can motivate providers to settle disputes rather than force you into litigation.
What if I’ve been paying the higher rate for over a year before I noticed?
The length of time you’ve been paying an improper rate without objecting can affect your case but doesn’t necessarily bar recovery. The provider might argue that you acquiesced to the new rate by continuing to pay it, or that you waived your objection by waiting so long to complain. However, courts generally require clear evidence of knowing acquiescence or waiver. If you can show that you didn’t carefully review invoices or that the charges were confusing or not obviously improper, you can argue that the delay doesn’t constitute waiver. You may face challenges recovering charges that fall outside applicable statutes of limitations, which is why it’s important to catch billing problems as early as possible. Focus your demand on the clearest examples of improper charges and emphasize that you’re also demanding correction going forward to prevent continued violations. Some recovery is better than no recovery, and providers are often willing to provide partial credits for older charges if you agree to a reasonable settlement.
What documentation should I keep during the dispute process?
Document absolutely everything related to the dispute. Keep copies of your demand letter and any responses. Screenshot or save PDF copies of any online account pages showing your current charges or plan details. Save every email, text, or chat transcript with the provider’s representatives. If you have phone conversations, take detailed notes immediately afterward including the date, time, representative’s name, and what was discussed. Keep a log of when you sent communications and when you received responses. If you file complaints with regulatory agencies, keep copies of the complaints and any responses. If you dispute charges with your card issuer, keep copies of the dispute paperwork and any correspondence with the bank. This documentation serves multiple purposes: it proves you made good faith efforts to resolve the dispute, it can be used as evidence if you end up in court or arbitration, it helps you remember details if the dispute drags on for months, and it demonstrates to the provider that you’re organized and serious.
What if the provider tries to send me to collections over the disputed charges?
Being sent to collections over disputed charges that you legitimately don’t owe is unfortunately common. If a collection agency contacts you, you have rights under the Fair Debt Collection Practices Act. Send the collector a debt validation letter within 30 days of their first contact, demanding proof that the debt is valid. Explain that the charges are disputed and provide a brief summary of why they’re improper. Send them copies of your contract and your demand letter to the original provider. The collector must stop collection efforts until they provide validation. If they report the disputed debt to credit bureaus, you can dispute it with the bureaus and provide your evidence that the charges are improper. Keep records of all communications with collectors. If a collector violates the FDCPA by continuing collection efforts without validating the debt or by making false statements, you can file a complaint with the CFPB and potentially sue the collector for FDCPA violations.
By following the strategies outlined in this guide, you’ll be well-equipped to challenge improper charges, recover money you’re owed, and protect yourself from future billing problems. Remember that the key to success is thorough documentation, clear communication of the factual and legal basis for your demand, and willingness to escalate systematically if the provider doesn’t respond appropriately. Most billing disputes can be resolved with a well-crafted demand letter, but knowing your escalation options gives you the confidence and leverage to stand firm when you’re in the right.
