Hypothetical question

Looking for advice on a legal issue in Tennessee. Here's what happened.

Square terminated my account. I've been dealing with this for about 12 weeks now and the situation isn't improving.

The amount being held/disputed is approximately $19,983. I have tried contacting their legal department 3 times with no resolution.

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

Illustrative response

Just want to point out — the statute of limitations might be a factor here. In some states it's as short as 1-2 years. Don't sit on this too long.
