Hypothetical question

I've been trying to resolve this on my own but I'm stuck.

scope creep with no amendment. I've been dealing with this for about 13 weeks now and the situation isn't improving.

The contract was signed 12 months ago. I have a copy of the original agreement. The total amount in dispute is approximately $112,000.

Am I overthinking this or is this a real legal issue worth pursuing?

Illustrative response

For anyone overwhelmed by teh legal process: break it into steps. (1) Gather all documents, (2) Write a timeline of events, (3) Research applicable laws, (4) Send a demand letter, (5) If no response, escalate to regulatory complaint or court. You don't have to do everything at once.
