ADSL and telephone line fault - two weeks in, no response

My ADSL and telephone line have been down since 17 February 2018. Both faults were logged on the very same day. Despite daily follow ups from my side, Telkom has failed to assign a technician to resolve the problem for over two weeks now. I run my business from home and it is costing me a fortune to buy 3G mobile data to stay afloat. On top of that, Telkom is quick to send me an invoice for the monthly bill to pay for a service I don't receive! If I had to tell my customers I would attend to their issue "as soon as possible", and leave them waiting for more than two weeks, I would be out of business within a month. Service delivery is optional when you have a monopoly - thankfully fibre will arrive in my area soon and I will not hesitate to switch for a second and be another unhappy customer that leaves Telkom.
