Bad service and wrongfully charging customers

No matter what, never sign up with RAIN. Their services are month to month which means if you dont make a payment you wont be able to use their services. For the whole month of January I didn't use the WiFi as I have not paid it because their prices are ridiculously high and when the weather is bad they network doesn't work at all. To my surprise today, I am billed for January and now my debt is double. How come? What am I being charged for if my WiFi and their services was disconnected ? Rain is ****ming customers and they are causing customers *****ulent debts.
