Auto-Renewal Subscription Trap - contractor abandoned project halfway

Quick background on my situation — any input appreciated ngl.

contractor abandoned project halfway. I've been dealing with this for about 9 months 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 $73,000.

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

I went through almost the exact same thing.

I ended up escalating to a supervisor/manager (at least in my experience), which cost about $1-3 but saved me a lot more in the long run.
