failure to terminate my contract

I called MTN in March to terminate my contract and was told that I could only terminate in July as the contract ends August and 1 months' notice period is given. On 13/07/22 I called MTN and gave notice to terminate the contract. I recently found out that that was not actioned, and debit orders still continued to deduct monthly. 17/11/22 I called and was told the termination was not done and was only done 17/11/22. I requested that the call I made 13/07 be retrieved and listen to and the agent I spoke to confirmed escalated the matter to a supervisor who will retrieve the recording of the call and call me back the same day. reference: 1-**********6. Until today I have not received and feedback or callback. I want my money refunded to me because this is their lack of competence, ******* and dishonesty from MTN. Mtn again debited in November.
