There is a money back guarantee on eBay. If you item doesn't match then open a return. It's quite easy to do, there are huge blue buttons practically in your face the moment you make a purchase on here, asking if you want to return your item. You don't need to contact the seller, although it was nice that you tried to. Since they were not helpful in guiding you correctly, then just open a return. Go to your purchase history, upper right under My eBay. Just follow the prompts. Best of luck to you....
