billing inconsistency

As far as I know, if my account runs from the 25th of each month and I don't pay on the 25th it means I don't want the service for the following month and my service gets cut. It has always been like this over the years that I have been a customer. In October multichoice did not cut my service until the 14th of october. When I paid for November they used that money I paid to pay themselves back for the days of October. This has never happened. They have now cut my service on the 2nd of November which is very inconsistent with their claim that the system is automated to cut off your service. I never asked them to cut off my TV on the 14th of october so why should I be made to pay for it, ESPECIALLY because I received NO NOTICE of an account in arrears or their plan to backpack themselves for days that I DID NOT ASK FOR. I paid for November and I would like my service reinstated for November. If you had wanted the back pay you should have notified me accordingly and ask for a payment plan.
