Terrible service

My line has been down since 14/12/2015, I was promised that technicians are attending to it when I last called on the 22nd. Today when I called I was told companies were closed in December, so my problem will only be fixed on the 31st Jan. I need both my phone and internet for my business. I can't help patients with medical aid. They go to the next pharmacy and I may never see them again. Plus, Telkom never updates me. Had I not called today, how would I know that they will only fix my problem on January 31st? Tsebo pharmacy
