Prescribed debt information not removed off ITC

I app**** for prescription with Nedbank and after being told initially the debt had not prescribed I had to provide them with the new credit act rules and their legal department eventually came back and confirmed the debt had prescribed. It was confirmed in writing by Regan Munnik that the debt had prescribed and my ITC records would be updated accordingly. Which I knew of course. I have been following up and now they are stalling saying they need confirmation from their ITC department that its being removed. In the interim I have sent through Nedbanks confirmation via email to XDS that the debt has in fact prescribed and when the lady phoned Regan Munnik at Nedbank to confirm he asked her to hang on. Hang on for what? the debt has prescribed it should not be reflecting on my records simple as that. I am highly irritated with having to wait for them to do what is legally required of them.
