good luck getting your money back .. ebay will allow the seller to continue until they don't pay their bill .. you will be told by ebay/paypal to return your item via expensive tracked airmail postage to the seller and politely ask for an exchange or refund at ytheir descretion .. I have been down this road too and have seenliterally  thousands of ebay buyers scammed via ebay china on this particular scam .. unfortunately ebay does such a great job of protecting scammers identities that I have no idea which seller you are referring to, but at a guess your seller is located in China, the land of free international postage and no ebay fees ..
