Cancelation, no Telkom do not do cancelations

Telkom purposefully making it hard as possible to cancel their service. I have logged a cancelation for my ADSL line since we are getting Fibre installed. I have received the reference number and have called them multiple times. But they seem to be unable to actually put the cancelation on the system.

This on a ADSL and telephone line that has been dead multiple times in the last 2 weeks alone.
