Telkom - ********** activity | Debiting my account for services not rendered

If there was a negative star, I would select that option. I have a contracted with Telkom that ended on 2 October 2020, I notified Telkom in August already that I will not be renewing this contract. Telkom has continued to debit my account for 3 months, even though I've received reference numbers stating that the contract is cancelled. This is ***** - debiting users for services which are not being rendered. Absolute theft. After speaking to multiple people in Telkom, this issue is still not resolved.
