******* and ********* behaviour

My connection was cut off because I forgot to pay. I decided that I was sick of DStv anyway and that I would just leave it off. Over a month later I start getting calls from Shapiro Sheik DeFries debt collectors regarding Multichoice. Then they demand my ID number "so that they know who they are talking to". I told them to get lost. I get another call, I put down the phone. Then I go online and see that my account reflects a balance of about R600.. I call them and establish that this amount is to reconnect and for the balance of the month. In other words, I have been handed over to debt collectors to get money for a service I have not received! This is clearly *******. DStv told me I have to phone in and cancel my subscription. I told them that nowhere on their website does it say that or in fact say anything about how to cancel your subscription. I told them that there is no legal way to sue me for money for a service that I have not received and then did cancel my subscription. Then they tell me that I owe R115.23 for the pro rata service I received. So I paid that and told them they would never see me again. I am beyond disgusted with DStv, its no wonder that they are losing subscribers.
