I first bought a domain by using BIN in this forum and met a scammer. He have not responsed me for over 1 week after my payment. I'm so disappointed on it. I already issue a dispute in Paypal and hope to get my money back. Also I want to leave a negative feedback to warn other people. But I got "you do not have permission to access this page". So frustrated. The seller has good feedbacks before except the recent deals. Can anyone tell me how I can trust somebody enough to buy domains in this forum? Thanks.
