DSTV (multichoice) complain

I want to put in a complain to the service I receive from DSTV this weekend. They cut our service without let us know. We have a debit order for at least 30 years or more with them and all of a sudden our TV was off without les us know. They make a falt on theire side by deduct R97 last month they have to deduct R970. They didn't come back to us to say they make a falt sorry, then we won't have a problem. Just cut us off. Before I pay the rest of the amount, I want them to come back to me and apologize, but nothing. The people at the call centre check our payment history and there was no problem for more than 30 years. Now al of a sudden it's my problem to pay before they put our sugnal on. There is no way I can even speak to somone at the accounts department. They send in a complain and will phone me in 72 ours???? Why??? They want premium payments, then we want premium service. I appreciate it if simeone can let me know wat to do next, because if we just pay they won't bother to come back to me.
