Hypothetical question

Quick background on my situation — any input appreciated.

merchant account terminated without explanation. I've been dealing with this for about 3 weeks now and the situation isn't improving.

The amount being held/disputed is approximately $40,644. I have tried contacting customer support 3 times with no resolution.

Has anyone been through something similar? What worked for you?

NAL, but from what I've read, you should check your state's specific laws. But don't just take my word for it, get real legal advice.

Oh god, another one of these.

Here's where people usually go wrong is having everything documented. I'd recommend keeping a detailed timeline instead.

Following this thread closely. The amount of practical information here is amazing. Much better than the generic advice I've seen elsewhere.

Pro tip: if your payment processor tells you "funds will be available in 90-120 days," that's usually a rolling hold. New transactions extend the clock. Stop processing through that account immediately.
