What do you want to happen?
Your only option through Ebay is to open a return on the grounds that the item arrived damaged.
The seller could choose to accept the return, get the item back and potentially claim against the postage company.
They could offer you a partial refund.
Do bear in mind that if you can't repair the item to your satisfaction, you would not be able to return it as it has to be returned in the same condition.
"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)
