Just a word of caution, if you're pursuing legal actions, you might consider not posting about any details publicly. Talk to your lawyer before you do anything...
I thought about that, but I've said nothing here that would hinder my case. They outright stole from me, and then when I called them on it, they responded with extortion. They aren't in a great legal position.

Any good lawyer will tell you the same piece of advice: "never say anything." It does absolutely zero positive good for your case and can only serve to hinder it later. It's very difficult sometimes to keep from providing what you consider to be valuable feedback for others, but you have your own interests to consider first.
