Be very wary of buying from John Lewis on line. From our recent experience, if anything goes wrong, they don't want to know. After failed delivery slots and the eventual delivery of damaged goods by incompetent installers I have wasted hours of my time on the phone being put on hold, waiting for return calls that never came and waiting for replies to emails with something other than a standard assurance that 'someone will get back to me' which, in spite of their own time limits, they fail to do. We have been treated with utter contempt and given endless, stalling platitudes and promises that they are 'looking in to it' The truth seems to be that once they have your money, that is that! Their customer service stinks and makes a complete joke of their customer care ethic. I have all the above supported with documentation and am trying to get contact with a senior manager in the company who may actually care! Take a chance if you like with your purchase but expect nothing but problems if anything goes wrong!
