Hi all, I'm new to these forums but, having seen all the great advice being given on other threads, I'm hopeful somebody can help me here. I recently noticed that I get charged for my line rental twice per month, a couple of days apart. Exactly the same fee taken out both times. I got in contact with o2 and, to my surprise, they revealed that the second charge was for a new contract I had taken out with CPW last April, and for a completely different mobile number. I only have one phone, and have used the same number since 2009 (which was issued to me by CPW, incidentally.) What happened was I 'upgraded' through CPW last April, assuming that it was a straight upgrade using my current number. I had already upgraded with CPW in 2011, with no issues. As far as I was aware, then, I had simply upgraded to a new handset. When I checked my o2 account online a couple of days after this, there was an 'upgrade' option. I thought this was odd since I had just upgraded through CPW and had switched my sim over into my new handset. The option was still there a week or so later and, thinking that maybe my CPW upgrade hadn't registered with o2, I clicked it. I then selected my tariff and completed the upgrade. All sorted, I thought. Now, the reason I only recently noticed my double monthly charge is because o2 gave me a £150 discount off my bill when I clicked their upgrade option. So for several months this didn't register in my account. The o2 advisor I spoke to (and it took a bit of explaining to get them to understand the issue) said that I am liable to pay the second contract even if I don't use it, because it is a fixed fee regardless. This I understand. The issue is the actual existence of the second contract. As far as I was aware, I had simply upgraded my old number and not at any point taken out a new contract. It was only when the advisor confirmed that a) I have two accounts b) I have two numbers and c) the CPW contract was a new one, not an upgrade, that it became clear. o2 offered to cancel my second contract for a cool £292. As I said, I distinctly registered for an upgrade with CPW, NOT a new contract. There was no issues with this in 2011, and I followed exactly the same process in 2013, so why had they issued a new contract? My question, therefore, is was are my rights here? I am paying for a service that I do not use, nor did I explicitly request. Is it too late to act? I'm a bit annoyed that I've only just noticed this. I've seen one or two posts around the web where customers have incorrectly been given a new contract and not an upgrade - something to do with more commission on new ones. Thanks for any advice offered.
