My mum went through the exact same story a few years back. She was overcharged to the tune of £800, they did not budge until she called watchdog and it was sorted within the half hour.
Surely they should offer more flexibility, as they often overcharge people under the guise of spreading out the cost throughout the year and give you affordable bills during winter. Well I think that's more like a smoke screen for them to score more money than what is due, and when it is due.
I don't think you should be penalised for their lack of accurate estimates. They should have sent someone to read the meter. I think you have reasonable grounds to complain.

Anyone else find their bill statements extremely hard to understand?
