Neff gas hob ignition would not work, was out of warranty so i called neff to come and repair, they sent a engineer to come and diagnose fault, the transformer needed replacing, to access the transformer, he had to remove the glass top, which was held down by 11 screws which screwed down on each of the burners , like bull in a china shop he sheared 2 screws off and damaged the glass top, low and behold now i need the two burners replacing and the screws, re booked visit with new burners, stripped the hob down to install burners then the engineer realised he did not order replacement screws for the one that sheared off, so no go, 3 weeks and £200 later i got a working hob, would never use them again, would not even recommend them to someone i hate
