I bought iMac from him through ebay, he sold me the iMac with a hardware problem and it didn't work. I reported that to ebay and ebay said you have to return it to the seller. He started play games and refused to sent the label through ebay and he said he doesn't know how to do that even he has ebay since 2002.
Finlay after ebay refunded me the money he sent me the return label. after that he stared play another game by sending a photos for a damaged computer (The photos were for different model not the one I ordered and start asking for the money back and he called me on the phone even that is against ebay rules and gave me a bad review in google trying to effect my business.
This guy is not trusted person at all.
(I have all documents and photos that proof what I said)
