MDB Claiming Amounts That I Do Not Owe

I did not want to give this business even a single star. They have been making my life a misery for over ten years. They have created two amounts at the credit bureaus, claiming that I owe roughly R46000 against two Absa credit cards. For years I have been blocking their messages and deleting their emails. One of the credit bureaus expunged their claims from my record but MDB simply put them back again. Appeals to the other credit bureaus have gone unanswered. I want MDB to remove the claims from my credit record, failing which I will take legal steps to further expose this ******** enterprise.
