I have waited over two hours on the phone to try and update my payment details, when I finally got through they hung up immediately, I am NOT IMPRESSED I have been trying for days to do it on line, and I am not stupid, but I just cannot do it. I am a very frustrated/angry customer. I am at the end of my patience trying to update a simple request for my payment details. What do I have to do. In future I will pay my account as it comes in rather than go through the dreadful rigmarole that I have just been put through.
