Telkom suspends our line for no valid reason and does not want to reconnect it

We have been having trouble for a month now with our Telkom line. They suspended our Sedgefield line in the beginning of August. They reconnected it and then suspended it again at the end of August. Three different operators give three different reasons for the suspension of our Telkom line. When phoning again with a reference number, they say that the reference number does not exist (but just yesterday I inquired with that SAME reference number!) They have no valid reason for the suspension of the line. Because of this, we have lost 3 business days so far. Very unprofessional!
