When they try to sell you a new phone don't be kidded by the comment from the salesman saying 'we will take care of everything'. What they do is sell you something then when it doesn't quite work out YOU have to chase the provider not them. I quizzed the salesman on the phone several times before buying the new handset as I had been conned the last time with the cost of a new contract when the old one ran out. Paying an upfront sum and a final bill, only to have a few days later another bill from O2. As expected their reply - go and ask O2! This is the last time I will ever use carephonewarehouse.
