I am an attorney. Here is some free legal advice. Forget about district attorneys and Attorneys General. They will not give a hoot about this case, unless possibly they have many complaints coming in such that it appears to be a scam. And even then, it is difficult to get them interested. My recommendation is to file a small claims case for breach of contract and conversion in your state and then serve the complaint on the company. Small Claims court generally handles cases involving $10K or less (varies from state to state), and is designed for people to represent themselves. In fact, in California, people are precluded from having attorneys in court with them for Small Claims cases. That will likely get their attention, and if it does not, you'll get a judgment by default for $5,000 plus costs. Name the guy personally as well as the company and you can record the lien on his house. THAT will most definitely get his attention.
