Ebay give you just 30 days to return an item and most payment providers give you 120 days to start a chargeback for a faulty item.
If you bought from a UK business seller, Citizens Advice might be able to suggest 'next steps'.
If you have contacted the seller, and they won't help, if it was a new item, you could even try the manufacturer.
"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)
