Fault logged 12 January 2018- Still outstanding. HELP

On 12/1 2018 I registered a fault with Telkom. I then received a fault number 419CTZ12018 . The technician contacted me and we confirmed the problem. Sadly, I am still waiting for the fault to be rectified. I have been to the local Telkom shop and they give me a ticket and state that someone will contact me to fix the fault. Again, still waiting. I then stopped paying my account as the registered fault was never solved. I don't NEED a Telkom line but I would like one. I now receive daily calls from debt collection companies to pay the outstanding amount which increases each call due to interest on the outstanding amount. My preference is that we solve this fault, come to an amicable agreement and continue with the logical business. HELP
