They've done exactly the same to me and trying to get O2 to sort it out has been an absolute nightmare. They even registered it as a new account on my credit file which also hammers your score, and to make matters worse they've since registered me as missing payments when I never received a bill and didn't even know there even was a balance!

that is rubbish Merlin isn't it. I had the same too - a hard search and new account without permission. I am going to go to the ombudsman when I find out which one it is. I suspect it may be the financial one as they did the o2 thing to me.
