The worst service provider in South Africa, by far!

Telkom fibre is spotty at best. Now I wish to cancel my contract. However, it is an impossible task, as you have to have a line number to be able to do that! I don't have a line number, only fibre! Their AI is so useless. I have now tried for 2 hours to just find out how to cancel and what it is going to cost me! I will never do business with Telkom again.
