Bought samsung smart curved tv.few weeks ago. Having checked on features including ch 4 catch up. Had call out personnel at a cost as could not access app. They told me immediately that not available on Samsung st moment and I had been mis sold. That someone would call back. After two days eventually called them. On phone half hour passed from person to person and eventually went to store. Four diff tech people on telephone and two floor staff all told me diff things and conflicting info. Was Told most staff are temps as coming up to Christmas. Most of telephone staff supportive but passed me over to someone else. The store told me no one buys a tv for the channels they can provide! Eventually given the basic amazonfire stick as a sweetener and a temp measure but no refund of call out charge. Supposedly Samsung will eventually update. I will wait and see but I will not rush back to John Lewis for anyghing as the customer support does not exist anymore.
