Hey everyone, I'm not sure what to do here, because this is a first for me. So any advice would be greatly appreciated. A few weeks ago, a guy from China won an ebay auction from me. He sent an echeck to my paypal, and once it cleared, I shipped the package immediately and even insured it for him, since it wasn't being insured. I sent the guy the tracking number. 4-5 days later the package returned, because the postmaster didn't scan the confirmation number or something like that, and it was mailed back out. Yesterday, he sent me a message saying that the confirmation number has no record. I checked the number myself, and says "has no record." Before I can even talk to the postmaster about this, he has opened a paypal dispute about this. It's been 3 weeks, and he's flipping out about this. Any advice?
