Atrocious Service Delivery from Telkom Fault Reporting Department

We currently have two lines with Telkom which were installed in March 2016. These lines have not been working since 3 May 2016. I have logged a fault with the Fault Reporting Department having these reference numbers: 81CWK 030 516 and 82CWK 03 05 16. I have been calling this department at least 3 times a day since the fault was logged. Each time I call them, I get told the same thing: that the lines have been tested and a fault has been found. When I ask as to when, a technician is going to be assigned to fix the fault, every service agent I speak to, has no clue! I find it absolutely ridiculous that it can take 3 days (and counting!) to assign a technician to my fault requests. These lines are completely dead resulting in me not able to make or receive calls or even access the internet, for that matter. I am losing hundreds of rands along with my valued clients, by the hour as I am unable to run my business properly. I really need someone with authority and the correct expertise within Telkom to look into my issue and have it resolved speedily.
