Absolutely criminal! They are actually robbing scumbags!! They changed our tariff from £200 to £500 without even telling us.. Now we are in debt to other people we was paying money out to with a direct debit because we was unaware there were insignificant funds in our account. They chose to take out ALL of this money as a GUESS on how much we may pay now that its winter (Its been winter every year thanks very much!) Then i asked to change back to my old tariff - so they did (that was then recorded on my account) and then today 1st Dec - they chose to ignore ALL of that and take out £500 again without telling us AGAIN! Another 2 hour telephone conversation later - they have said they cannot refund me i have to take to my bank. EDF will clearly got bust soon if they are in such desperate need to TAKE AND TAKE AND TAKE which is just karma for them. But this should not be happening to innocent people trying to pay their bills and now being caused such grief and stress at Christmas - let alone anytime of the year.
