Just to add to the good advice given to open that case for item not as described..... Does Not Match Description or Photos, eBay read all messages going through their system. If this buyer blatantly admitted to a scam, eBay will read this and probably act, though you will not see any results, but he could easily receive selling restrictions or a ban.
With the case, do not close it early, for any excuse or promise the seller may give, and do not forget to escalate on day 4, if there is no return label or refund from the seller.
