Bad customer service

Towards the end of last year I did not pay nor dis I use ur services as money was tight. To my understanding this is a month to month service and no pay no service so I did not mind knowing that il only be in arears with that one month unpaid. I did not use the service after that. I planned to use again after i can afford the month im in arears with n the next months debit but to my suprise i was billed for three months or more and that time no one was busy using the service. I want to see where in your terms n conditions does it show that I am still liable to pay for months where the services was not used. If a month is not paid why carry on to provide the service. Also want you to show me if devices were connected while you billed me. I called into your offices n to date I am still waiting for reply on all my emails

Okay thank you. If it is possible please show me...as I want to take this up with my family to ask why they made use of the se .also tell me why you kept providing service when you did not get your premium the 1st month??
