That is the downside of buying from Ebay - you can return faulty items for up to 30 days but after that, it is between you and the seller.

"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)
