Telkom is becoming Eskom

I have been trying to sort out my internet connection for one week now. I have been calling the technical department everyday 3 times a day and this fault was allegedly escalated to upper management. No one manager has had the decency to call back. One week later and having told them I will cancel their services, I still have no manager having common decency to call me back. This after me being a loyal paying telkom customer for the past 20 years
