Telkom inefficiency

I signed a contract with Telkom to provide an internet service for me. We had problems from day one with the Internet always down and not working. To date my Internet has been down for 2 months and every time I call the 10210 number it’s always the same story that they will dispatch a technician out. I have complained and been calling on a daily basis and even went to their offices. But no one can assist me I been sent back to the same 10210 where I’m always told a technician will be dispatched. I want out of the contract since they have not honored their part but am told I have to pay the remaining months. Reference for the call I logged with them on 05/06/18 is ********** 4. On Monday I spoke to a Manager Thando Dlamini who promised to personally call me back and sort it out but it never happened. Yesterday I spoke to Anne Yolisa who promised the same and today to Leabona who promised to escalate further. Please assist as I’m paying for this service that is not available to me and the staff is not helpful at all
