rude and unhelpful operators

I called the multichoice call centre regarding my walka 7 channels. Both operators were extremely rude and unhelpful and kept speaking in circles. I have 2 walka 7 devices and had MNET channel on both. All of a sudden today I only had MNET on 1. I was told by the 1st operator that its impossible as only 1 device could have had MNET and the 2nd operator told me that only old customers would have MNET. I regard myself as an old customer as Ive had the devices for over 2 years now. Seems as if they don't know what they talking about. What is the purpose of having a walka and paying for something you don't have. The clever operator then tried to tell me that is was forfeited due to the fact that I had it disconnected which is utter nonsense, Ive been a client of multichoice for over years and my service has never been suspended. I have also googled the available channels for the walka 7 and MNET is stated as one of the channels. When I mentioned it to the operator he told me that there is more than one MNET channel and then I lost my patience with him because he kept on trying to make me out as an idiot. I've lost all respect for the call centre and still don't have a resolution.
