I sold a guitar head on eBay and shipped it out. The USPS tracking number says it was delivered on the 4th of this month. Today(the 13th)received a message from the buyer saying he wants a full refund because I didn't get a signature requirement on it. He says it never got into his house and somebody must have stolen it off his door step. I did not get insurance on it. And in reality I think it's not my fault and I should not pay for it. He didn't ask for insurance on it nor did he ask for the signature requirement or post office hold on it because he lives in an urban area prone to thieves. I don't think losing the head is worth the positive feedback, and I think he's lying.
