I recently sold my 13" Macbook Air on Amazon marketplace. The guy paid, I sent off the macbook and everything was fine. Then about 2 days later the buyer started complaining saying it was too scratched and that I didn't describe it accurately, and he wanted to return it to me. I accepted the return and told him to send it back and I will give a full refund. A few days later I received an amazon claim from him, saying that I have not refunded him yet, even though I received the item. But at that point, I had not received anything. Anyway, I told amazon this and they asked the buyer for a tracking number, which he provided and showed that I had signed for it. But I had not received anything from him and told amazon this again. Then a few days later amazon said that he had provided a receipt which shows that he sent a parcel with the weight of a macbook inside, and I had received it (which I had not)! Amazon refunded the buyer, so now he has my macbook AND money! I contacted the police but they basically said that they can't do anything since he didn't physically rob me. Is there anything else I can do?
