Cancellation not done

Good day <br> <br> I trust that you are well, I just got a call from Telkom telling me that my account which I cancelled last year is in arrears. This here is incompetence someone didn't do their job so I said to the lady can cell this thing and I will query it she says to me that I must pay my account and then she will cancel it which is ridiculous. I canceled this account last year sometime at gateway Telkom they called the cancellation department and then they said that they will cancel it and put it on prepaid or something. I was moving to pmb and my parents didn't need the phone or wifi any longer. There was absolutely no usage on the line cause there is no phone at my parents place and now I get a call telling me that this account is still active. This is unacceptable, you guys need to investigate this and resolve it I will not pay for something that I did not use. And I want this cancelled and prove provided to me this time
