Line out of order - 8 days and counting - zero feedback!

On Wednesday the 23rd of August 2017 I reported my faulty Telkom line and received reference number 143ATK230817 with a 72 hour service SLA. After 72 hours I was told that it is a cable problem and that the fault was passed on to the cabling department, a technician would contact me. Today is day 8, I have called in every single day (takes on average 15 minutes to speak to a call centre agent), to be repeatedly told the same thing - a technician will call me. The call centre agents are all very well trained and I think would really like to get resolution, however, there are either not enough technicians or my technician has just decided that I can wait..... but nothing is happening. What else must I do???? I cannot work (no data), I cannot make calls (Vodacom reception at my house is so pathetic that there is a 100% chance that my call will drop at least once during a conversation), I cannot get to speak to a technician even when I drive to a place with Vodacom reception. PLEASE PLEASE HELP!!!
