Gassy and grumbling

I tend to wait a while before trusting the gas and electric companies with a direct debit instead of bills, as they often go a bit bonkers. EDF had been okay for a year, so I graced them with a direct debit. They promptly went bonkers and billed me based on an "Actual" reading of 6235, which is quite a bit above the meter's current reading of 5108. Plz to be refunding me £330. Grr.
