Cancellation nightmare

Good day,

I’ve had trouble with Telkom and their nonsensical cancelling of service for what seems like forever now. My contract expired last year July/August. Since then I’ve been trying to cancel, in vain. Which has led to me being billed ending up in arrears( we know what that does to the credit score) and also hinders the cancellation process. So in my attempt to try and settle my things, I paid the account on 08/01/2021 so I can proceed with the cancellation. And now when I try to go ahead and cancel in their stupid App, it tells me there’s an error retrieving my details and to try again, this has been going on for 3 WEEKS now. I’m so frustrated, I just want my number converted to prepaid and cut my contractual ties with your company. And when you call their customer service, they don’t even care to find out, they direct you to do it online, as if they themselves know what the process entails. This complaint is what seems like my last resort, I have been trying and it’s getting very frustrating now.
