ABSA Internal Systems reflects wrong information

ABSA refuse to update their internal systems whereby they remove my debt restructuring status. I have send through my paid up letter to them on my ABSA personal loan to their credit bureau department I received a message back that this was resolved under ref: C-***7 but when I try to apply for a credit card the status remain unchanged and my application gets declined. I am not under debt restructuring on any credit bureau but ABSA claims it is not their fault that the system shows this.
