My partner bought a Nokia T20 tablet online for our Granddaughter and after 3 months it would not turn on. Contacted John Lewis and was appaled by their response. They basically told us we had to physically return it to a store to be sent to Nokia (our nearest is 25 miles away and they would not accept at Waitrose] or post it to a store at our own risk and expense or deal with Nokia direct. I would advise the buyer to beware because the John Lewis guarantee is not worth the paper it is written on. We have always purchased from John Lewis due to the precevied additional protection that we believed wrongly to exist but will shop elsewhere now.
