Please help cancellation of our business account!

Hi. We would like to cancel our bussines account. We filled cancellation form and also send supporting documents to telkom cancellation mail. We got auto response but nothing else. While we are busy back and forth with Telkom Bussines Account cancellation, got sms from Telkom Nudebt collection and they says we need to pay them. Now, yes we would like to close our business account and pay all outstanding debt but HOW? Can someone please assist because almost impossible to reach Telkom Businesses Cancelation. Kind Regards.
