Nedbank card division miserable customer service

I had a credit card with Nedbank and the account was overdue during the first quarter of last year and most parts of 2021, due to financial difficulties experienced when my wife was unemployed in 2021. They handed over my account to their lawyers, and they reached out to me for a payment arrangement which we concluded. I started of paying around R1500 as an initial agreement, but have since doubled the instalments to R3000 pm. I have recently checked my credit record with one of the credit bureau, to my surprise my information about the repayments I have made to date is not being updated, and Nedbank has actually listed the said account as if I am no longer repaying it while they are busy collecting my repayments of R3000 every month. I need Nedbank to update the information on credit bureau accordingly as I diligently make this monthly instalment. I received a very poor service from two of their consultants from the card division recently. They hanged up the phone on me as soon as I requested to talk to their manager, seeing that they were unable to address my issue. One of the consultant names was Zakhele, I did not get their surname. I get statements every month from Nedbank to reflect my payments, but they are simply not willing to update my information on credit bureau accordingly! I want to know which legislation allows them to abuse our rights as consumers. Nedbank has a responsibility to present my information on credit bureau in a fair, consistent and accurate manner. What they are busy doing is in violation of the Fair Credit Reporting act.
