False information reported by yoiur accounts department to credit baearo

I have an account with you, last month I was supposed to pay 710, so i paid R500 and had a late payment of R250 which I ended up paying after a few day. Your credit department has reported to the credi beauro that my account was on arreas for one month which is incorecct. There has been a month that I had skipped a payment in the year 2025. It should have been reported as a late payment. Kindly clarify which month did i not not pay?
