The fact that the seller copied the exact same photo from another seller's listing doesn't in itself make the listing fraudulent. eBay now allows any seller to copy and use any other seller's photos and descriptions.

It would have helped us to help you if you had explained exactly how and when you paid, and what response you received to your cancellation request.

Has the seller agreed to this - through eBay, not just in messages? If they disn't agree to your request to cancel you will have to wait until after the latest estimated delivery date, then if it hasnt arrived open an item not received case under eBay's money back guarantee. If it arrives, but doesn't match the description, you can open an item not as described case instead. Otherwise you can only return it if the seller's returns policy in the listing is to accept returns. Unless, of course, it was delivered after the latest estimated delivery date, when eBay will entitle you to treat is as not as described and return it under the money back guarantee.

All of the above assumes that you were not misled into payng by bank transfer, which would remove all protection provided by eBay.
