Telkom's very very poor service

I registered a fault with telkom 3 weeks ago. I call them everyday and they're not telling me what is the problem and when is it going to be fixed. It's so frustrating calling them , you hold for a very very long time and they will send you from pillar to post. It seems their staff have no clue regarding their work, each one will give you a different story, some will transfer you to their sales department and that department does not take calls at all. I was told that I need to get the integrated data sim card, I went to one of their stores and I was turned back because I didn't have proof of residence after I drove for kilometers. No one told me that it was needed. That sim card is also not working, I called them and went to their stores and they're still giving me different stories. This is really frustrating , I dont know what to do anymore.
