over a yr ago my eldest, same name as me, asked me to get a mobile phone (sim only) contract for him. he said he would pay me each month adding that if he didn't it was only a 30 day contract. i did but he didn't pay. i warned him that i would cancel if he didn't pay me. and warned him, and warned him. over a yr later i told him i was cancelling the contract and, eventually, i wrote to O2 asking them to cancel. i explained to them that it was my son's mobile on my Homephone & broadband account with payments being taken from my account. i even explained he had promised to pay for it but never did and that was why i wanted to cancel. rather than waste the 30 cancellation period i asked if it could be transferred to my daughters iphone. i had emailed the O2 CEOs office as when i had previously tried discussing this with their customer "services" they had called my son on his mobile who had told them it was all a misunderstanding. someone senior called me from the "CEO's team", i again explained son's mobile contract, my landline & BB, my bank account, cancelling as son hadn't paid me, we both had the same name and that my son had not lived with me for yrs (about 10). they were great! not only could they transfer the contract to my daughters iphone but they could also change the package, with immediate effect. and, as my sons blackberry addons would no longer be needed, they would cancel them. happy! happy! happy! then a letter arrived so i opened it. it was from O2 confirming a new contract, for a new mobile number, £35.74 pm for 24 months. checked the name, me. bank sort code, mine. account ... didn't recognise it. so i checked, not my account. then i remembered, my son has an account at the same branch. it was the only bank that i have ever been able to persuade them to distinguish between us when they send mail, they had agreed to add a sufix to his name. i digress. so i emailed the person who had sorted out the previous problem. i said i had received a thick letter from O2, which i had initially thought was junk mail, but then realised it was confirming a new contract and then said: "now i really am confused. i'm quite sure that i had explained to you that i was cancelling my sons blackberry contract because he hadn't paid me. yes, you kindly transferred that contract to my daughters iphone. why on earth would now you think that i might want to start a new contract for him? even worse, why would i possibly want to commit to a 24 month contract when he hadn't been paying me on the 30 day notice one? my eldest son has not lived with me since ... he was 13 yrs old. he has no right to be using my address. if he wants a contract them he should be using her address or the manchester address where he spends a lot of his time." O2 rang me back, again Ronan Dunne's team, to say that they had "spoken to the O2 fraud department". they could not do anything unless i reported the situation to the police and called O2 back with the crime number. did O2 not have a duty of care ? i told them we have the same name. i told them he didn't live at my address. i told them i cancelled his sim as he hadn't paid me. surely they should have applied a little common sense ? surely they should not have allowed him to open an even more expensive account. surely this must be wrong. and surely i should not need to report my son police. isn;t there a cooling off period? why couldn't they simply cancel the whole contract on that basis? p.s. i've also a letter from Orange, seems he's opened an account there too. however, one phone call and they said i won't receive any more letters from them except one to say that everything is cancelled.
