What is better a electric key meter or quartely payments?

ComEd has been reading my meter wrong for over a year, now I'm paying for the mistake!?

• I just received a $400+ bill from ComEd. I have made all my payments on time. So I called ComEd to see why I suddenly have an increase in my bill. I was informed that they had been reading the wrong meter for over a year and that what I have been paying was not the correct amount. Now I have to pay the new balance. I explained to them that I should not have to pay this because it is the technicians fault and not mine. Is there anything I can do. Why do I have to pay for their mistake? I am really bothered by this. Where has customer service gone, or the old saying the customer is always right? At this point I am taking this to a supervisor level, but I need to know what kind of ground I stand on?

• Answer:

  You probably should pay it since you did use that electricity, but they should allow you to spread it out over a year or so since they messed the readings up for a year.
