Disappointing experience with We Buy Cars

After a first successful purchase at Webuycars, they finally caught me out with the 2nd purchase. I bought, what they advertised as a 2007 Honda XR 250 motorcycle, to find out later that it is a 1993 model. Even though the Natis documents show 2007, Honda SA confirmed from the VIN number that it is indeed a 1993 model. I obviously overpaid for the motorcycle, but Webuycars refused to correct the pricing. They referred me to their online complaints department that have failed to provide any feedback. Another faceless company that you don't get any responses from. Very disappointing.
