Nothing, but that's the problem.
I sent the fairings back and he got them on the 16th. I rang him and he said he had 30 days to refund and wasn't going to do anything till then. That came and went so I got in touch with Visa card services (I paid on my bank debit card), they asked for all the details. I sent them that, waited a week and rang them. They won't cover the purchase because it's second hand items.
So now I'm onto trading standards who just say write to him as a prelude to sueing ....

that sucks balls mate.
how much are you out for then ?

i know its not the $$ as such but more the principal.
can you at least get them back if he wont cough up ?
the childish option could be buy the rest of his stuff and fuck him about likewise

It's not really practical he sell lots of stuff and has over 8000 possative feedback.
You'd have thought somebody like that would just swear a bit refund and get on with their life, huh ? Still he says the items are relisted due to a "fruit loop" messing him about

Opps !!! Doh !!!
Ok I went to the bank and asked them to check my account - they asked how much I expected back I told them they checked ... not in. But when I asked them to check again for any money coming in they found a payment.
Really the "rules" say I should have got the postage costs as well (£15) but I haven't ... that said I'm not going to chase them for that.

So the lesson - Go through e-bay and use Paypal

glad you got most of your money back chap
and another one for the black list
