I sold concert tickets on ebay to someone back in February. The concert was two weeks ago in June. I just got an ebay dispute saying he did not receive his item. I emailed him back saying he never let me know he never received the tickets, and now it is two weeks after the concert. I could have transferred them electronically if he never received them. I do not have the USPS tracking number. I only have his address and my address, of course. Has anyone been in a situation like this or does anyone have any suggestions? Thanks.
