How does Telkom still have clients?

It baffles me how they still hold the monopoly over provision for household internet. I am not blessed to have a fibre connection as yet but I swear once it becomes available I am switching over. I logged a call 4 weeks ago, they send a technician a week later. I get notified my fault is resolved- It was not. I phone again informing them my 10mbps line only runs on a measly 0.98mbps. I wait another week for a technician and still no resolve. It is utter bull**** and anyone reading my other reviews will see how bad my experience with Telkom is. These guys are the worst. Not to mention you sit for 30 minutes on call trying to get hold of anyone in technical.
