Am I going to lose this case on EBay?

This was my auction.

The guy waited 22 days after the auction closed to contact me about the item. I tried to compromise with him; I needed him to either return the (If he agreed I was going to send him money for the shipping) or a picture of the item confirming what he said. He refused to do either of those. He said he threw it out because it was damaged (he said some battery acid spilled on the games). The games were delivered to his parents house and his mom opened it, he was out of state when the package arrived. I can’t tell if he’s lying or not that’s why I needed a return or a picture, at first he left a few things out about the condition of the item and then he gave me inaccurate information. I tried to be civilized with him, but he just kept insulting me. I can’t refund him his money without either a return or a picture of the item as he described it.

I’m going to lose this case, right? EBay is going to side with the customer, even without any proof, right? Do I have any chance?
