FIX MY LINE

My business line is unable to make or receive calls.I logged a fault on my line on 15.07.15 Ref 523CRK150715. On the 23.07.15 I received an sms to say its been resolved. IT was still not working.The very same day I called the call centre. and was given a new reference 382CRK230715. on the 24.07.15 I received another sms to say service had been restored. It still wasn't working. The same day I received another sms from telkom saying that a network outage was affecting my area Ref 5405. On the 29.07.15 I received an sms saying the problem had been resolved. Still not working. I called again 03.08.15 Ref 577CRK030815. To date still not working. Each time I have called I have held on for 30 mins from my cell phone because my telkom line doesnt work. I have requested to speak to Supervisors, who are always on training or in a meeting.I'm still waiting for a supervisor or manager to call me back. NOTHING!!! You expect me to pay for a service I havent been able to use. My business is suffering because I can't use my number. HELP ME!!!
