Telkom has no concept of customer service

My Telkom phone line and ADSL line has been out of service since 12/09/2015. I reported the line the same day (259CRK120915). On the following Monday they closed the Fault without verifying with me if the problem was resolved. I had to log another fault (314CRK140915) for them to investigate. On tuesday after calling about 3 times to get answers i received a call for one of the consultants who requested me to do some testing. After that no more calls received from Telkom. I had to call every single day and sometimes twice a day for feedback. Twice I spoke to supervisors and still no feedback and no commitment to their promises. Not once does Telkom take the initiative to update their customers on the progress of the faults. Everyday I called, I received the same story, they're in the process of assigning a technician to the fault. I know we always complain about Eskom keeping us in the dark, at least they notify us when and for how long they are going to do it. Telkom has no sense of customer service. Please advise who I need to contact to cancel my service. Thank you
