Unable to Cancel TELKOM ADSL Line

Dear Team Peter, I requested to cancel Telkom ADSL line, on call with consultant NOZITHO confirm me that due to collections line is put under suspension status, but Every month a Debit order for Telkom is processing at last day, Response from call center is worst, they will tell us issue will be escalated and nothing will happen, I am really really not happy with the service from Telkom. If we cancel the debit order this will effect our credit bureau, is there any forum that I can raise a complaint on Telkom about their services. Much appreciate of your assistance on this, i want to cancel the connection with Telkom and get my money back from them.
