TELKOM: Unauthorized cancellation of Fibre, and not doing anything to fix the problem

Telkom cancelled our Fibre with Vumatel, without any authorization to do so. We have now been without internet connection since the 30th of July. I have phoned numerous times, each time getting another excuse, and then told that the issue was going to be escalated to the supervisor to solve. Nobody does anything to re-connect me, and nobody even acknowledges receipt of any of the emails that I sent.
