Cancelation for account ***

I was under the impression that my account was cancelled since I submitted all the forms on 27 September 2017. It has been 2 and a half months. My line ********** was not working in November, why was I billed for November? Under the consumer act it is ******** to continue to bill and ignore my requests for cancelation (as indicated below) as I has given 1 month notice as required and it has been 21 business days, as you indicated it will take to cancel my service. I have done my contractual and obligated part to fill in the forms, let Telkom now and followed the proper channels. As of yet, I have not received any communication back from Telkom and was billed anyway.
