What I am supposed to do?
It's too late now to do anything through eBay. The time limit for a money back guaramtee caim is 30 days.
Even if you paid by PayPal, it's now a few days too late to use Paypal's much longer, 180 day buyer protection policy.
We don't know how this pappened, but I'm afraid you've allowed two, rock-solid guarantees of a refund slip away. As you paid in Euros, the seller must be outside the UK so you can't even use the small claims court.
Good luck, but I really have no idea what else you can do.
