It a nightmare to cancel a mobile contract that is about to expire

I wanted to cancel my existing mobile contract as it was expiring this end October. I was given so many different stories when I called to cancel my contract and eventually I was told that cancel it online which is not working. I sent a screen shot to telkom representative below that there was no option to cancel contract but no feed back from her. She promised to escalate this matter to her team leader and that was the end of it. She is now ignoring my emails when I am trying follow up on this matter. That is very unprofessional and poor customer service.
