Hi KC1, I'm sorry to hear about the situation. This is not something that occurs normally and needs to be investigated further to resolve this once and for all. Instances like this happens when a neighboring property signs up with an energy retailer providing your property's meter details. This could range anywhere from the meter being labelled incorrectly, incorrect meter details in the national database etc. I will send you a private message shortly to discuss further. Cheers, Deepesh
