ABSA Paid up Account - Still Blacklisted

I have paid up my account that was in arrears in November 2017. Now I am struggling to clear my name on ITC and credit bureaus. After several calls and emails I am still struggling. I am transferred from one department to another. The attorneys that handled this account was LGR Incorporated. They send me a paid up letter to confirm that my account was fully paid up in November 2017. They also put a judgment on my name. Now they would not help me to get it off my name. They are quick to blacklist people but do not care what happen after that. I've send the paid up letter to Absa's credit bureau department several times, but they still did not clear my name. What can I do to get them to do their work to clear my name?
