Vodacom doesnt want to close my paid up account

I paid up my contract 18.02.2024 and closed it, only to find out today that the same account is at pre legal. I have been sending emails to the Vodacom customer center and early cancellation ever since because i was receiving invoices. They only stopped sending invoices but did not update their records. see communication below:

Which error should I fix? I am working in sales not cancellations. Did you send the cancellation forms to the cancellation department?
