Charged for a Multichoice mistake

Let me start of by saying that i was under the impression that multichoice is a \pay as you go"supplier<br> We went on holiday in the first week of April. We decided not to pay a subscription to multichoice seeing as we are going to be away for 3 weeks. Last week i recieved an sms from Multichoice requested payment on services. I phoned the next day and spoke to a lady and afterwards i spoke to a \""manager\"" with the name of Andile. I asked them why my services has not been suspended after the payment was not done the 2nd. They had no answer to that of course. They indicated to me that there were no faults on their systems showing any \""late terminations\"" of services. I was rudely told that this is my mistake as i was suppose to phone and cancel services. And that i would have to pay the outstanding monies is i want my services to be activated again. This is ****************! And i refuse to pay for a mistake from Mutichoice side. The best part is last month i forgot to make payment and my services was cut of on the 6th?? It has happened in the past that i pay late and services has never not been suspended?"""
