I've been with n power for the last 3 years. I set up a direct debit and was always in credit. Only after viewing my statement from my bank i realised no payments had been taken by n power!
When i rang to enquire about this, they said my dd had been cancelled!, and not by me!
Please be careful everyone as this could have led to debt out of control!
I'm so disappointed and looking elsewhere as I've had no apology!
