Telkom cancellations

I had a LTE/Data contract with telkom, which i cancelled online way back in January/February 2024, I am now being handed over.!!!! I phoned telkom, said on their side it has not been cancelled, which they have now done and I must speak to the billings department re: outstanding amout (which has now amounted to over R4000!!!!!!!!) Billings department says i must speak to cancellations department, who do i speak to? I am not willing to pay this, why have an option online to cancel when this happens. I am not happy right now, we also have a fiber line, which should just cancel now if this is the service you get. Is there anyone who has a contact that can help?
