I've had such amazing service from John Lewis in the past that I was totally shocked and disappointed with my latest experience. I recently purchased a TV from their online store. I very carefully removed it from the packaging making sure to maintain its immaculate condition to test the picture quality. When I was unsatisfied I called them to arrange an exchange for a different model - one that was more than double the price - and was obviously prepared and happy to pay the difference. The customer service representative informed me that it wouldn't be possible to replace the TV as it was not in a saleable condition. How is one supposed to know whether they are happy with a product by simply looking at the sealed box?! DO NOT buy expensive technical products from John Lewis, they will be of no help to you if you are unsatisfied, even if you're trying to give them more money. I will not be doing business with them ever again.
