Duke Energy Progress review: over charging

My light bill doubled this month from last month and the excuse your reps give is that the weather. It was not even cold for the most part of November. The meter read double than last month and then I checked it 5 days later and it was already up 500 kw. That is not normal. I have checked all breakers one at a time and in groups and nothing changes the kw usage. I requested my meter be checked and was told some outlandish line about it either slowing down or stopping, like it can't speed up. Duke Energy Progress is money sucking vultures that bleed the consumer dry. When there is no competition you charge people whatever you want because you know there is no other options for people who are on a fixed income and limited options.
