Now I know why they are listed as 76th best (ha!) mobile phone shop on Trustpilot. Had a SIM only contract £6 per month, and was offered an upgrade, over £17 with a new phone. Supposed 14-day cooling off period. 2 days later, I notifed Carphone Warehouse, both in-store and by phone, that I had changed my mind and wanted to cancel the upgrade. So I didn't get a new phone (obviously), but am now paying almost 3 times as much as I should be paying, and don't even have the new phone! And locked into the worst possible contract for the next 2 years!!! Whenever I contact Customer services by phone, they say that I must go to the store, where I was originally to pick up my new phone. Predictably, when I go to the store, they say that because I had arranged the upgrade on the phone, I must call customer services again. Need I go on??? Their stores and Customer services are like two separate organizations that don't speak to each other. Nobody wants to help me. I really don't like to leave negative reviews, but the way I have been completely ignored, with empty promises that someone would call me back, have left me really frustrated. How are other customers, with less experience, going to find them... I dread to think. I notice that whenever others leave negative reviews for Carphone Warehouse on this site, they offer a pathetic apology and try to give the impression that these are isolated incidents, but the facts speak for themselves. Their standard response: 'We are very sorry to hear about the issues with your order, at Carphone Warehouse and Curry's we pride ourselves at putting the customers at the heart of everything we do and unfortunately we have fallen short on this occasion which we apologize for.' This insincerity on their part only adds insult to injury. Their treatment of these people is inexcusable. My advice... Have nothing to do with this wretched company.
