Re: "The company kept very quiet"
Oh god, British Gas are *awful* at everything.
We moved into a new place, and the renting agent "helpfully" phoned British Gas to give them readings.
Except, he read the wrong dial, and so gave them a 5 figure number, where the previous reading had been 6 figures. To compound things further, their previous reading had been estimated anyway.
Did they flag it and say "errr, that's not right?" Did they bollocks, they allowed the number to wrap around, increment back up to aforementioned 6 digit number and then sent *me* a stonking bill. Didn't really trust the letting agent not to screw it up a second time, so I gave them a heads up and said I'd sort it and then pass on the revised bill.
Fairly easy thing to explain away, except you can't actually speak to the buggers because they've seem to have paid a consultant who's told them that speaking to customers is bad, all you need is a website, an email bot and a very minimal and well hidden phone team.
The fact *I* also took a reading when we moved in, and had the reading of *both* dials did me no good
What eventually solved it was me telling them what my calculation of our usage was, saying I'd pay them that but we're changing provider and they can take me to court and defend their position if they want to try and claim we'd used thousands of £ of leccy juice in the space of a couple of weeks.
