I ordered front brake discs and pads online for a Corsa using the registration of the vehicle to identify. The discs fitted well but the pads were the wrong shape to be fitted. Took the pads back to the shop but was told because I ordered them online through click and collect they could not exchange them and I had to buy the correct parts again for £36. I was told I should have measured the parts before ordering which would have meant removing the wheel, dismantling the caliper to comply for measuring. Ridiculous. The pads box had been opened previously and one set of pads had already had the plastic protection removed, so presumably another customer had encountered the same problem. The registration of the car should have been sufficient to match the correct parts, so the online connection for the vehicle is wrong on your system. I have purchased similar parts for a different vehicle without problem. I left the pads I was not able to fit with the shop to dispose of. I shall never use your online system again.
