Telkom not dealing with my broadband fibre issue

I currently have a 100 Mbps Uncapped fibre account (which I want to update to the 200 Mbps line.)

I have contacted Telkom on six separate occasions stating that the current line speed is incorrect and running up to 70% slower than what it should be. I have all of the line speed tests to prove this and I have invited Telkom to my house to come check the line.

As yet, nothing at all has been done about it and I still face issues on a weekly basis with my line.

As far as the CPA is concerned, this is breach of contract and I should have no problem at all in cancelling my 24 month account. Telkom, do you plan on fixing this?
