Help getting money back from seller

[lolsteve]

Thanks guys , don't want to be a dick..but not go too soft that he says no.
It was a bit foolish of me but I spent the last of my wages on these hoping to have them on and sorted for this weekend at 3 sisters circuit..obviously thats not going to happen now so feels like I've just spunked away all my money
Also since fitting them and being shaken about for a week the drivers side window has come loose and is rattling
