Bad service

I reported an issue about my telkom landline in the first week of december 2015 and i was promised a technician will be sent to solve the issue within a week and was given a reference number which is ***.<br> A week later i called the center again to follow up on my query and i was again told they will send a technician to have a look at the issue within a week and nobody came.<br> I called the third time and i was give an escalation reference number which is *** and i was reassured that a technician will truly come this time and no technician has been to my place to have a look at the issue.<br> Its now 11 of January 2016 and the issue is still not solved, we use the landline to run our home based business and at this current moment we are losing customers because our landline is not working at all.<br> Can this issue be resolved please.
