This is the same company as Carphone Warehouse, from whom my son bought a mobile phone some years ago. After almost a year, they phoned him and offered him an upgrade, about which I knew nothing until it arrived. My son is mentally handicapped and could not have answered any security questions, as he doesn't know the answers, not even his own date of birth. The "upgrade" was not as good as the phone he already had and when I rang them and got past the usual crap of "I can't talk to you; you are not the account holder", I was not only told that he had answered security questions, which is quite frankly impossible, but that they couldn't listen to their recording of the conversation as there were too many of them to dig through.
Anyone hearing him on the phone would know that he had no idea what they were talking about.
I will have nothing whatever to do with this company, or its offshoots. What has Stephen got to say about this?
