Can I still use them? It says on the back of the last (insane) bill I got, in my handwriting "rung 15th Aug-meter readings...."-and then gives the meter readings for the 15th Aug. I know I rang up the automated thing with them as they were so different from the estimated ones, and I can remember ringing with readings at some point so it must have been then, but then I have been sent a bill that still puts them as estimated, and gives me a bill of £800. According to my readings I have used 228 day units and 239 night units since the 15th Aug, but according to their estimates I have used 3196 day and 1698 night units. I don't live their any more, is there anything I can do?
