My debt hero put my under debt review when I have settled my accounts

I phoned my debt hero in 2022.. I had 2 debts that I couldn't manage.. I arranged to work with them (depositing money into their account then they settle then they settle my debts monthly) i ended up changing my mind and deposited the money into my 2accounts that I was in debt with (telkom, Finchoice).. I paid up all my debt in 2024 towards year end... My account were closed and I was given delisting letters... But my credit score did not increase and I could not qualify for a mere R100 credit... 4 months after settling my debts credit score goes down by 20 points.. I call NCR asking them what is happening.. They told me my debt hero has put you under debt review (with no communication, they don't check if i had paid my debts... Imagine being under debt review when you owe no one) im very upset and i advise you to never ever use these so called debt counselors... It is better to make an arrangement with the ones you owe.. And you end up paying them more money and they pay your debt collectors less money so that they pocket the rest, nothing is for free. And you'll end up in my situation being under debt review and score decreasing when you have settled your accounts. Especially my debt hero... Their reviews are horrible.
