I purchased a sim free Samsung for my wife. After six months the phone developed a fault. I returned it to the shop and they said it had to be sent to "Geek Squad". When it was returned the body of the phone had been broken, there being a finger nail sized piece of it missing. After much discussion they agreed that it had not been like it when they sent it for repair so the repair team would replace it. They would call me within 5 working days. After 7 working days I had had no call so I called them. I was told that it was waiting for me to collect it in store. I went to get it but, after some time, the assistant told me that it wasn't in store but was still on the way. Two days later I called again and was assured that it was now in store for collection. Went in to be told that they "couldn't find it". Admitted that it had been signed for in store but tried to blame "the Christmas rush" for losing it. Was assured that the issue would be resolved within 72 hours. Today I went again to be told that no investigation had been started and that they need another 72 hours to sort it out. I heard the "manager" telling the assistant who was serving me that "Chris" had signed for it on the 20th (the day before I last went in to collect it) I asked why they couldn't just ask Chris where he had put it, whereupon the told me that there was nobody by the name of Chris in the store. They clearly think that their customers are both stupid and of no value. DO NOT SHOP AT CARPHONE WAREHOUSE IF YOU VALUE YOUR TIME OR YOUR SANITY
