Paid up account giving me bad scoring

I app**** for car finance, I was declined. One of the banks that declined me was Standard Bank, I called your call center, to understand why my application was not successful. As far as I know I do not have any outstanding accounts, I have a paid up car that was financed with SBVAF, fair enough I did not bank with standard bank. I left Standard Bank after many years of banking with Standard Bank because they did not approve a home loan I had app**** for. FNB approved my home loan and so I moved on. That was over 6 years ago. Fast forward 6 years later, your legal department did not update their records, the Fiesta was paid up in 2014 and I had a written letter from your legal department and secondly, I am have sent the letter to ITC to update their records. When I called today, the call center agent mentioned that car that was paid up in 2014!!!! What do I have to do for Standard Bank to update their records. Please sort this out ASAP! The scoring was low because of the \owed amount\" and no one bothered to ask for my bank statements or lease agreement to support my request for car finance to substantiate the decline, or lease agreement to see my additional income of R 10 000.
