I had a similar incident with a buyer in Belgium. I shipped via USPS but no delivery confirmation and no signature required. There was however a customs tracking number. The buyer received my item with customs due upon receipt, so he refused the item (or so he claimed). I never received the item and he opened up a claim and E-bay tried to charge me back for the loss... Long story short, I contacted them by phone (Paypal) which was not easy, and provided the customs tracking number to them. They verified my side of the story which was as I stated above. They told me that the buyer was protected and that I would have to pay him back. I told them to once again repeat the chain of events as described above, and that I would sooner cancel my Paypal and E-bay account than to pay this guy. They said that their policy always protects the buyer, so I changed tactics on them and agreed that the buyer should be protected and that since I had a tracking number that they confirmed as good I should be protected as well. They agreed to settle with the buyer and not charge me. It was a long and difficult process but it can be done. If you have an hour to waste on the phone, I would recommend trying to use the customs number for tracking and get Paypal/E-bay involved. Good Luck, Scott.
