Telkom

I have cancelled my smart broadband wireless last year on the 10th September 2020. They have responded to my email on the 17th September to confirm that it has been cancelled. However, they are still billing me every month after I called in numerous times and emailed numerous times. They confirmed over the phone as well that it has been cancelled and I cannot seem to get hold of them or anyone that can assist me as everyone I talk to is telling me different things or transferring me to a voicemail line where they want me to leave a message.
