ABSA LISTING FALSE INFORMATION ON CREDIT PROFILE!

I do not understand how ABSA operates! You have sold my personal loan account to another company and I now pay the company whom the account was sold to for the outstanding amount yet you go and list false information on my credit profile as if the account is still with you. Not only does the account not belong to you any longer but the amount listed there is completely wrong as the account is almost paid up with the company who bought it! I am working hard on rebuilding my credit score now you come and damage it unneccessarily by listing false information on it. Each month I look at my credit score is has gone down because of the false information ABSA is listing on it. This is totally unacceptable and is prejudicial to me. Please remove this false information from my credit profile immediately!!
