aaa auto Dontell george aka Dj aka moose stole my money by selling me a defective transmission west monroe, Louisiana

I gave dontell 450.00 for a transmission for my 2001 dodge 1500 and waited for about 3 weeks for a defective part . I was assured a 1 yr warranty and i tried returning within 5days , only to be told i wasn't getting my money back. What hurts me the most is he's engaged to my sister and i didn't think he'd stoop that low as to scam me.This has not only cost me an additional 1150.00 but a relationship with my sister as well. My sister is COMPLETELY INNOCENT and he needs to be stopped . I may not ever recover this loss but maybe it'll get something done or save the next customer a loss.
