Numerous failed attempts to cancel my Telkom subscription

I've heard from numerous people what a nightmare it is to cancel a Telkom subscription. I listened to such stories with some disbelief - after all, how can a company have such atrocious service? I unfortunately got to experience this firsthand when I moved cities and needed to cancel my Telkom subscription.

I put in a request to cancel my Telkom subscription on the 21st of June 2017. I filled in the cancellation form and included a copy of my ID. All that I was asked to do, I have done and then some. To date - after numerous phone calls and assurances from Telkom - my account has still not been cancelled. Three different service consultants agreed that there was nothing outstanding from my end and asked me to forward my initial email to cancellations promising to chase up on the matter.

Despite not having used the service since the end of June 2017, I am still being billed. This is completely unacceptable. I am at my wits end how I can resolve this matter.
