You should be able to access the original listing page even after the auction has closed. Usually you can do this by visiting your account page on the auction site and reviewing your winning bids. You may also be able to find a link to it in previous emails you received about the auction. Once you find the original listing, compare the photos and item information to what you received. Before you contact the seller or request a refund, make sure the error was the seller’s and not yours.
