They need to look at customers rights
bought a lens online .delivery was quick and well boxed. used the lens for 30 mins and the camera rejected the lens saying there was a fault i removed the lens about 5 times to reset the camera. and it kept doing it i went to my local shop to ask for a refund. and they refused saying it had to be tested first! I asked was it not tested yesterday when it was delivered out. still waiting for refund. first and last time i will buy of these
