Business ProfileforSJR Contracting

We did enter into an agreement well over a year ago, but we have had discussions before the year was up, where the contractor, Scott Driscoll, has apologized and told us a variety of reasons that he delayed (to put it mildly) in responding back to us , and to doing any work, and that his partner lied and caused him business problems. He also cited a divorce from his wife as a reason and him being depressed and embarrassed of his situation (being taken advantage of by his partner), as reasons why he was delinquent in addressing my emails, calls and texts. Since then, we have tried to move forward to do the work, but again, he's totally non responsive at all again. Now, after paying about $12,000 as a deposit to buy materials he has told me that he has no credit and I have to buy the windows, etc. from another distributor, ADK Sales. Before buying the windows, I've requested his promise that he'll be available to remove and install the windows and he agreed, but has not responded in a long time since then. We've already invested over $12,000, over 2 years ago, and were promised that he would abide by our contract, but this is still continuing. I've asked for my money back and he says he can't do that, and yet he isn't doing any work either. I've paid about $12,000 for absolutely no work done and no promise of work to be done as he's not responding to phone calls, text messages, and emails. I've left many messages of all forms since mid December and no word back. I don't know what to do and just want to be done with this and have my money back at this point to pursue actually getting the work done by a reliable contractor. I'd also like to help prevent anyone else from having this done to them in the future.
