Lack of communication

I app**** online for a preapproval for vehicle finance. My credit record was not too great but I have rectified most of my past expenses and my experian report looks clear as well as transunion. My application was declined and I was given no reason as to why. By law creditors are supposed to give exact details on what basis the application has been declined as I can see no errors on both my latest reports.

When I called and asked the agent why it was declined I was given no answer. I would like to know the reasons why so if there are errors I can take it up with the bureaus. Standard bank your service is bad nd may just have to check at nedbank or fnb who would probably be more helpful. Can I please get a response to my question.
