Seller fraud

Won a ps4 console auction and the description stated in perfect working order now seller is claiming product is defective and has lost a game included in the sale and told me i could cancel it if i didn’t want it which obviously I didn’t anymore. I told him to cancel it himself cuz i as a buyer didn’t have a valid reason to cancel i.e (product defective) now he canceled the order and put reason as “buyer asked to cancel”. I can’t find any support on ebay to contact them to avoid my account getting suspended. How do i go about this? Any help is greatly appreciated.
