Unless you are still within 30 days of the purchase of this item on eBay you cannot open any case for a refund.
You unfortunately bought a fake, and listing it eBay took it down, you must not relist it or you'll face serious selling restrictions.
Are you within 30 days of the original purchase? Then, open a case for item not as described, item does not match description and escalate on day 4 if not refunded beforehand.
