Telkom cannot take simple debit order instructions

I run a call centre and when we changed our phone lines we duly completed our monthly debit order forms. Our line has been suspended on 2 occasions now because of the billing departments incompetence to act on a simple instruction to collect the debit order from our account. To top it all I come in to the Telkom branch in Cresta Mall and they want me to call the call centre to help me. Come on Telkom get your act together or put in systems and internal controls that works not frustrate your business clients operations.
