Anyone ever had one of these? I'm with e.on next, apparently. (Was with e.on, they've moved me over). I gave a meter reading in December 2020, they then reduced my direct debit by £20ish per month. Gave more readings in May and June, and between May and June I apparently used over 7000kwh. I'm pretty certain I didn't, and I've just got a bill through for £1200. Every other month I have data for it's something like 300kwh, so I'm at a loss to explain that.
Worth contesting? Is that even possible? Anyone else ever had one of these?
