Telkom does not appear to be able to repair faults

I have been logging faults with Telkom for over two weeks now. My landline is not working. They keep telling me that the problem has been resolved and that the fault has been closed. When asked to be put through to a supervisor (after holding the line for 25 minutes) I was then told the supervisor was out and would phone me back in 20 minutes. He never did. I am now going to patrol my neighbourhood until I find a Telkom technician and I will harass him until he comes to my house. I am really angry now. I have an 80 year old parent undergoing chemotherapy and need to be in daily contact. I pay extra to belong to Telkoms Closer service so that I can speak to my mother every day. To date I have spent over R300 just waiting for someone to pick up a phone on the Telkom side. I have to use my cellphone. Is there no other Telecoms company in this country. This is a pathetic lack of service. Are these people competent at all. I am a teacher and I teach their children. Bet they would have a lot to say if I didn't take my job seriously.
