I had a one year nightmare with O2 who have quite possibly the worst administrative organisation ever known which has to be experienced to be believed. Everything is fine as nothing goes wrong with your account - just pray that it never does. I can't begin to list all the bungling inefficiency I was forced to witness. Also don't expect them to give you the right information because they may not and my experience was they took zero responsibility whatsoever for their telephone operatives giving me completely the wrong information.
