Bypass the local Postmaster and file a fraud complaint online or by phone with the US Postal Inspectors. They will forward a copy of your complaint to the Postmaster at the Post Office where your package was received. The fraud will get investigated, and you will get a response to your complaint. Once you file the complaint online, I would call the Postmaster at the package receiving end to give him a heads up about the PI fraud complaint. He may have received other complaints relating to this same person. The Postal Inspectors resolved two cases for me very quickly, but in both of mine the delivery person failed to scan the package which was insured.
It would help us if we had an ebay ID for the buyer. I would also google the buyers address to see if it is located at a mail receiving business.
