Capitec ruining my credit report!!!!

I had a credit card with capitec which was handed over during covid due to non-payment. In 2021 I cleared the account and Capitec was notified. Debit orders stopped but this year I started being debited. I called in and was passed from pillar post. No answer. I was given the ref # **********17 that no one seems to know anything about. This matter resulted in the account reflecting in my credit report as open when for almost 2 years is was closed / inactive. At the beginning of the year the credit card was removed from my name and all the debits were refunded however it has been almost if not over 4 months now yet the credit card reflects on my credit score with a balance of R50.00!!!!
