Gave a deposit to a contractor for new siding on my house...never showed up to do the work, has not given my deposit back (as he said he would)

I gave a deposit of $8000.00 to Barncord Construction to replace the siding on my house on July 1 2020. Said they were going to start on July 5 2020. Never showed up..called repeatedly and he said they were delayed by weather (it hadn't rained here in over a week). Kept calling. texting, emailing, occasionally got a response of we were delayed by weather ....Finally told him after 3 weeks that I would find another contractor and he agreed to give me my money ($8000.00) back. Said it was in the mail...never arrived. Let him know that it never arrived and he said he would drop one by the house,,,that was 2 weeks ago. He has not returned calls, emails, texts. Please help!
