Disgusting service/no service

I had the most putrit service and experience trying to get assistance. I have been holding on the phone for hours to speak to an agent. My query requires telephonic assistance and the self help portal cannot resolve my current problem. I have already spend over R500.00 of airtime holding on and to listen to a computer messages.My subscription fee is R399.00 so I am in Lost here and still no internet. This is perthetic service. I completed a form send to update my details and it's still not done.
