Cancelled Telkom Contract, Paid Settlement...Service not Cancelled - Can't Get Assistance!!!!!!

I spoke to a telkom agent and requested a cancellation of my cellphone contract. The person told me the request to cancel was being processed. I was given a settlement amount, which I paid immediately. This was on 21 October 2022. Till today I have not received a confirmation that the service is cancelled. End of October telkom instead debited from the settlement I paid! I've been requesting call backs and trying to call with not luck or response. I got a call once and when I picked up, the call cancelled. I just need my contract cancelled ASAP!!!!!!
