After a landline / fibre has been installed, Telkom customer service drops to zero.
Telkom had teams in the street over my whole neighbourhood, offerering to upgrade from ADSL line to fibre at the same monthly cost as existing packages. I accepted and got fibre, but never signed for a different contract (more data, higher speed).
After a few months my invoice doubled, and it took me hours (yes HOURS) on the Telkom support line (10210) to get to anybody that could somewhat help me with the problem. I asked to be returned to my earlier monthly premium, or else for Telkom to prove that I have signed up for a more expensive package (which I have not).
Eventual answer from Telkom is that I should prove that I do not have an upgraded contract with them. How do you prove something that does not exist ?
