Multichoice Dstv misery

The worst service I have ever experienced! I am a premium subscriber for decades. Recently I enquired why I was not able to view Showmax which is an free add on to my subscription. I was informed that I would have to buy a new decoder.( Explora Ultra) Thenew decoder was installed on Monday. I have been calling the call centre since then to help me obtain a link to Showmax. Today I once again tried. Each call lasted more than 30 minutes. I requested to speak to a supervisor but was told to hold on longer. I then informed the lady that I was not prepared to hold on for another half an hour and requested a call back from the supervisor. Needless to mention that has not happened more than 2 hours later. I find this extremely unacceptable from such a large organization.
