Debt review flag at African Bank but not at any credit bureau in South Africa

Very disappointed with African Bank, I have been battling to prove to them that I am no longer on debt review since February, I app**** for credit card with them, I was told that their records shows that I am in debt review and they need a proof that I am no longer there. I called my then debt counselor and she wrote me a letter to confirm that I also contacted NCR and the sent me a screenshot of my record with them to show that I withdrew back in 2018. I have since paid those accounts including African bank ones, but they refuse to remove the flag now they say they want the admin order certificate which I do not have because I was never under admin. African bank if you guys can't help me just tell me instead of sending me from pillar to post, I am not flagged for debt review at any credit bureau in South Africa, but African Bank will not remove the flag on their records instead they want a letter straight from NCR kante do we have Debt counselors. If you can't help just say so.
