No service whatsoever

Our business telephone line has been non-functional for over 2 weeks now. We have logged the fault numerous times. Firstly trying to phone the call centre doesn't get you anywhere, today I phoned again and after over an 40 minutes of holding a line a consultant finally answered the phone only to tell me he will check the status of the fault, 20 minutes later after 61 minutes from the time I originally phoned he had still not come back to me. Since this isn't a toll free nr when phoning from a different line this is a call of over an hour that we will be billed for. Logging a fault on the online results in someone phoning back eventually however every time Telkom messes it up and sends the incorrect technician for a PIR system that we have cancelled well over 4 years ago already. I have advised them numerous times now that it is a plain Telkom line now and they should just send out a normal technician and every time I get promised this is what will happen and that a technician will come out but then no one does and when I check online they have simply closed the fault report as if it was fixed. We are losing lots of business as the line has been out for over 2 weeks now. Ridiculous!
