The fact that you bought it on eBay works in your favor. The seller is likely responsible for knowing the legality of what he is selling. If they aren't responsive, and if you used a credit card you can have it removed from your bill. EBay also has a buyers protective policy that you can look into. Your seller will likely want to work with you because you can also give him a negative rating on eBay which sellers hate to get. One way or another you are in the drivers seat.

"I love living. I have some problems with my life, but living is the best thing they've come up with so far." � Neil Simon,
