No Service, empty promises

My Mother's phone line has been down since beginning of December and our ADSL has been giving problems as well. We have logged this fault more than 10 times already, telkom technicians never show up. They never honor there appointments. After no service they still bill my mother. Telkom has to come fix this fault. My mother is in a wheelchair, and relies heavily on the use of her Landline. I want the Bill revised, and the fualt to be fixed.
