So I ordered items from a guy, they didnt match his description but I didnt notice for a few weeks. He said it would take a long time to do the refund over dhgate but he could return it directly to me. He says in order for him to do so i MUST send a message on dhagte ( we are talking on skype, he says I can't send it on skype) with my order number and payment amount. I don't understand, he is not a major popular seller, he should be able to pull up my order. Is this a scam?
