4 rally wheels and tires for small bolt pattern

Well, I think it's time for a mod to step in here. I'd appreciate any help that can be given to me. Jason cashed my check on June 21st. Tomorrow makes a month since he cashed it. He will not reply to my PMs to him or return my phone calls. I did business with him in good faith and he didn't hold up his end of the deal. He still has his wheels and tires and I'm out $700.
