I paid a mechanic to do some repairs on my car, but the repairs was not completed. After a month of calling and showing up at his garage, I was forced to have my car towed to another mechanic. I even ask him to just put the parts back in my car so I take it some where else. He refused to do any work on my car even though I had paid him in full. It was the weirdest thing I have ever experienced. He never returned the money I paid him either. Is there any way that I can recover the money i paid the mechanic? I don't have a receipt for the money I paid, but I have witnesses that can attest to what happened.
