There is a lot you can do with the help of Ebay and especialy if you used paypal to pay for it. Go into the help section of Ebay and file a dispute claim and that will have Ebay contact the seller and make him respond or you will get your money back. Paypal also has this feature and you can do either one , just follow the instructions.
I have used this option myself and can tell you that you will get action from Ebay
