Billed incorrectly

I am extremely fraustrated with Multichoice.I have 2 explora and Wi-Fi package,which amount to R1440 monthly .To date I have paid R1800 and my services are disconnected.I have made numerous calls to call center with no joy.I made like 15 calls to be exact between yesterday and this morning.the consultants have not idea what’s happening or rather they can’t read the screen in front of them.I have never seen so much incompetence in the whole call center it’s shocking.When you ask to speak to a manager you get told he/she is busy.what should one do in this instead?I am really fraustrated .can I please get someone competent in that company to please tell me what’s happening with my account.I am taking this to 702 now am really exhausted
