Frustrated Client

I had financed my car through ABSA VEHICLE FINANCE. I then paid and settled the account on the 30th June 2020. They sent me the paid up letter, they however have not updated my ITC records. The records show that I have arrears from 208/2019 and still owe the balance for the account. Each time I try to get assistance from them no one helps and this is very frustrating. This is affecting my ITC score negatively and stopping me from doing other thing since it shows delinquency on my records.
