I had over paid money into my account.......i was owed over £500, when I contacted them to get it back they said i had to wait a month then when i tried again it said i had to wai wait another month....so i did. After waiting 2 months i called to get my money back and they wanted a picture of my meter box before they could do it.......then they tell me there was a problem with the billing! I then owed them money APPARENTLY!! I have NEVER had such high bills!! I was then told that the manager would call me back, AND DID NOT!! RUDE!! Funny how there was a problem only when i wanted my money back! So they didn't pick this billing issue up on ANY of my meter readings? Or after the smart meter was installed?? REALLY?? I am a single mother of a 10 month old baby, on benefits!! And they just took what i had overpaid!! REALLY WOULDN'T RECOMMEND THIS COMPANY!!
