Telkom is seems out of control - it does not know its Back Office from its Front Office

I have had a fault on my fixed telephone line for nearly 3 weeks - no dial tone, and no incoming or outgoing calls. I have logged the fault by phone from work using 10210, also by using the Telkom app. - several times over 2.5 weeks. I have had a "chat session" with the call centre. Not once have I had a call back, an email or an SMS and the fault remains. I keep on paying this useless company monthly as I have done for 37 years, but I am apt to stop all services from Telkom including my ADSL service (which has been working curiously through all this time barring one or two brief outages) . The call centers do not seem to know what is going on and fob you off with a "the call is logged and a technician will be dispatched" - but nothing ever happens.
