Did you have to pay for the refund or did Ebay pay the buyer for the damaged item?
If Ebay refunded the buyer then I believe they will have told the buyer to keep or dispose of the item.
You can't keep the payment and expect the item back.
"There are two ways to be fooled. One is to believe what isn't true; the other is to refuse to believe what is true.”
Søren Kierkegaard, Danish philosopher (1813 - 1855)
