Almost feels like a scam this company. Paid my bill (to begin with overcharged by £130!). Kept getting emails telling me I hadn't paid the bill. When I called to query this and mentioned being overcharged in the first place I was more or less told that was my fault for not supplying the reading(I have a smart meter, isn't that the point of having one of those?) and that I needed to supply a bank statement as 'I might not be telling the truth'. Had to travel an hour there and back to the bank to get a statement to show them the amount that had been taken out on the 31st May. It's surreal. They operate on sheer greed bordering on aggression if you're payment is a day or two late , with threats of further action. Just nasty, soulless, heartless, really need some kind of regulation to stop them behaving like some kind of mafia.
