Hi @SoniaCG, welcome to neighbourhood.
If we've sent you saying something that says you have used more energy than you actually have, I apologise. Although from what it sounds it says you've spent more on your energy bill, which as you've pointed out can also mean an increase in rates as opposed to an increase in usage. If you are concerned about your rates, feel free to reach out to us here so that one of our agents can make sure you are on rates that are good for you!
Regards,
Mark.
