Poor service with Telkom - irratge customer

I honestly do not know what to do anymore. My moms business line went down on the 29th March. We reported it on the 30th March under reference 10CRK***. We then got another escalation reference number of 108211. We are now on the 8th April and the line and the ADS line are still not fixed. This has been escalated twice already and email (so they say) have been sent to the technician that has been assigned. Whenever we call that is all that we get told. A technician has been assigned. What would normally be a 48 hour turn around time, has now been over a week. Can someone else tell me what to do ??????? The service is absolutely shocking. we cannot even get hold of the supervisors or team leaders as they are supposedly working from home, When asked for a contact number of the technician it is also denied. They can't even tell me where the fault is or how much longer it is going to take to fix it.
