My dad did something similar with a strimmer from B&Q. After a couple of uses it packed up, and he could not get it going again. Unfortunately, he had lost the receipt and put the packaging on a bonfire, so we just bought another, swopped out the defective one and took it back saying it was faulty. Dad got a full refund no questions asked, and nothing was scanned. These things are just tossed in the bin by the retailers and classed as shrinkage.
