Yeah this happened to me once before also. Won a part on ebay, paid immediately via paypal, and that was the end of ever hearing anything from the seller. Like stated above, use the ebay resolution center. They will ask if you have contacted the seller through the ebay message center and if you haven't heard from the seller they will know. Then ebay tries to get in touch with them and it goes from there. I did receive a refund and I'm confident you will too. It really sucked though because like you I would have rather had the part than the hassle. I've been a member of ebay almost from the beginning and getting refunds in circumstances like this is always in the buyer's best interest. Back in the late 90's I had won a set of swing out tailgate doors for my '72 land cruiser, got in touch with the seller to get an address to send a money order to, and after a few days heard from him that he thought he should get more money because they were worth more than they were bid up to. Needless to say I didn't get the doors. Ebay has come along way since then!
