OP, the best course of action is to use an online authentication service, either authenticat4u ( which ebay recognise) or etinceler also ebay recognised. Once you have received your authentication result forward to ebay. You should have no problem getting your money back. Good luck.:-)

oops sorry, that's authenticate4u, missed the "e"

OP I hope you have contacted one of these services, they are by far the best in the business.
