Off Topic - USPS Problem/Receipt Question

[Baseball Rarities]

Leon - if this is not in the right spot, please feel free to move.

I have a neighbor (seriously, not me) whom I am trying to help out. He sold a $2K item just over two months ago (beginning of October) on ebay and shipped it out via USPS Priority Mail with Insurance.

He never uploaded the tracking information to ebay and no longer has the receipt. He just figured that the package was delivered since he never heard from the buyer.

Anyways, he got a message from ebay yesterday that the buyer says that he never received the item.

He paid for the shipping with a debit card, so it is on his statement, but that is all the proof that he has.

He went to his local Post Office and the clerk told him that they only have access to the last 30 days of info at their terminals so she referred him to the main branch in the neighboring city. He went down there and they said that they have no way to access his purchase or print up a duplicate receipt and said that his local branch would have to help him.

Obviously, this is all his fault, but I would think that there has to be some way to retrieve a copy of his original receipt with the tracking number on it.

Any suggestions?
