Nominal erroneous charges

I currently have a personal loan with Sanlam which I pay via a debit order and hhave never defaulted . In 2022 around May I downloaded my credit report and noticed there was an arrears amount of R59 on my account which of course negatively impact my credit record. I tried for months to reach them but to no avail and then noticed that month on month that nominal fee was increasing. I finally got through to a consultant that committed to resolving the problem which in fact happened but now I see the same R59 appearing again. I have tried endlessly to get this resolve and asked for an explanation but my issue is falling on deaf ears. Shocking client service and completely *********** !!!!!!!
