No accountability for bad service!

To date my grandmother's faulty line has still not been fixed. I have lost track of the amount of calls made to the call centre, the amount of promises from technicians, call centre agents as well as Management. The service Telkom provides has to be the most pathetic I have ever experienced. Lack of accountability to insane excuse from the technicians is absurd, and the fact that according the manger i spoke to earlier Mr Chris Govender, they unfortunately cannot be held responsible for the technicians not coming out when they suppose. I have about enough of the run around here. This call was logged on the 11 MAY 2015, It has been escalated, I have put the complaint on Hello Peter with still no joy, a Manager by the name of Sulayman called my grandmother on Thursday telling her that a technician will come out on Friday 12/06/2015.
