Disgusting company. I pay dual fuel by DD and they wildly vary the amount to be paid following review. This has been between £40, £110, £90 £70 and recently increased this to £115. Following the last agreed plan they took almost £200 from my account. I rang to complain. They admitted it was a mistake but were unable to help. Dealing with them is like talking to a crossword puzzle. Three times I rang them to be asked to speak to Customer complaints, and they hung up every time. I have now submitted a formal complaint by e-mail and asked to be contacted as a degree of urgency as they literally have money belonging to me that I can ill afford. To jump from £70 one month to £200 the next when they actually agreed £115 then deny the opportunity to rectify this is unwarranted and a disgrace. I refuse to pay good money to be treated like mess on a shoe by incompetent call handlers. I am going to cancel my DD and vote with my feet. I can see this complaint going all the way to the ombudsman.
