Had a similar problem with H20LRW
I bought some 4x4 cossie rear calipers in October/November
I sent loads of pm's emails etc, every time a different excuse.
So in December he says they must be lost in the post, so he says we will refund me.
Eventually on January 31st i get a refund.
But in this time he must of sent me 2 cheques that i never recieved and then after he refunds me through paypal he says he had sent another cheque and to just rip it up when it arrives, as you can guess this one never turned up either.
Oh well at least i got my money back in the end.
