I am on the budget plan. They update the rate stupidly. What I've paid over a period of time wasn't enough, so they more than doubled the amount I pay even though they know I just replaced my old HVAC system and my bills won't be as high. At one time I had paid too much over a period of time, then they lowered it by about half. If they would make the adjustments in smaller increments, maybe they wouldn't be adjusting it so much. It's just ridiculous.
