Payment expected for NON-EXISTING service

On 24 October 2019 I cancelled my Telkom line ***) with the understanding that I had to give 30 days notice - i.e. the service was suppose to be available to approximately 24 November. On the very next day, after cancellation, however, Telkom in their wisdom decided to cut the ADSL - the main reason for subscription. All efforts to have ADSL restored has failed yet an account, dated 9 November 2019 still charges me for services gor the period up to 8 December. This has frustrated me to the extend where I have, physically, ripped out the Telkom line yesterday. I hereby wish to declare that I have NO intention of paying this latest account - Telkom Accounts to please take note.
