Incompetence at its Best

I took finance out with ABSA for my car with correct banking details provided twice from the start. I have been sent a message after following up 3 times, that I will have a bad record for lack of payment on my part and yet ABSA has recorder the incorrect banking details. I have called 3 days in a row now to rectify the problem and sent them a copy of the contract signed with the correct details that they have on hand, and they still ask me, on every single call, to confirm and provide the correct details. Now a record will be shared with the credit bureau tarnishing my name when they are the *********** lot.
