Quite simply the worst company to have to deal with. They are so lucky that Londoner's have to use them otherwise they wouldn't have any customers. In the space of a year they have overcharged me, undercharged me, cancelled my account, cancelled my water supply, taken unauthorised money out of my bank, only paid some of it back etc. They also seem to have a completely untrained support team that have no idea how to do a simple task - put you through to someone else with no notes on what you've already discussed. Say they will call you back and then never do. Seriously just the worst.
