RCS ignores queries and refuses to fix their own mistakes!!

RCS incorrectly updated my bureau records to reflect 2 outstanding loans (when I had only taken 1). The records have different credit provider names (RCS - FIXED LONG TERM CASH LOANS and RCS GAME NAMIBIA) but refer to the same loan. I settled and closed my loan account within a month of opening it (opened on 19 June 2019 and settled on 10 July 2019) and even received a closure letter to confirm my account has been closed, however RCS does not seem to care about my bureau profile or correcting their own mistake of duplicating the records. I have sent more than 10 emails and follow ups with screenshots of my incorrect bureau records and my closure letter to the loanscustomerservice RCS email address but have not even received a single response to any of these since my first mail on 25/07/2019. The automated response says feedback will be provided within 48 hours yet it is more than a month later and still nothing. Up to today, there are still 2 records on my bureau profile FOR THE SAME LOAN. One now shows as closed and one shows as open and owing the full amount of the original loan (RCS GAME NAMIBIA). I have called them numerous times and only get cut off or redirected to other people and then get hung up on. I have also queried this on the website and yesterday I finally got to speak to a consultant after the card department called me regarding my website query and put me through to the loans department. Demi (I think her name was) from the loans department ensured me she would call me back within an hour after speaking to her manager but has still not called me back up to today. Please urgently REMOVE this from my credit record as it should never have been there in the first place. I only took ONE loan! Stop messing with people's bureau records and then ignoring requests to correct this made on every query platform. This is horrible customer service!

*Additional query - I closed my RCS Makro account many months ago and yet it also still reflects as open on my bureau record. I had to hold on a call to RCS for 1 and a half hours to get this account closed and yet my bureau record has still never been correctly updated. It shows a zero balance but if it was closed then why was it not updated to closed? I have also asked for this to be corrected telephonically a few months ago but nothing has been done. RCS just don't seem to care about customers.
