You have to pay VAT, no if's or buts, when I asked who I could speak to about this to get my VAT refunded the nice man at HMRC (no he really was a nice man) pointed out that the only one who could do anything about it was the chancellor of the exchequer, who was Alistair Darling at the time, so I paid up.
Make sure they send it back DHL, UPS or FedEx, there are no further delivery charges as with Parcel Farce, quite often there are no customs charges levied either unlike PF who seems to have a deal with HMRC to charge you for everything
If however you have a purchase receipt showing you paid VAT for the item in the first place you should be able to get away with paying no or a limited amount of VAT, how you avoid duty is another matter entirely
