Cancelled Vodacom account

On 5 August 2020, I cancelled my Vodacom contract with my last day as 30 September 2020. Another debit order went off for 1 October 2020 and another for 1 November 2020. I phoned and sent emails again to stop this account. An attorney phoned me today that I still owe Vodacom R236. Vodacom has never even come back to me after my queries per email when my account will finally closed. All I want from Vodacom is that someone can just contact me that we can clear and close this account now finally.
