Cancellation nightmare

I have been calling Telkom to cancel my fibre service for 2 weeks now, and when I spoke to an agent she said I should call 10210, when I call 10210 im told to call 10213 and vice versa. I dialed 10210 and followed voice prompts which don't take me to where I can cancel the service. I also made an online account to try an cancel but doesn't show the account or anything.. This is just made in a way so we can't cancel the service if we don't want it anymore, I'm just tired of the back and forth between agents who won't help me and automated voice prompts. Telkom has really bad customer service.
