Unhappy customer

I have been using rain for almost a year if not more and for the last few months they have been deducting multiple amounts of money from my account, iv been calling only to speak to a consultant who says but nothing reflects on our side. Why would I call every month about the same thing only to be lying?? Iv been told that a supervisor will call me back but nothing iv send my back statement more then a month ago and I still have not received any feedback not even an email. I am extremely disappointed.
