Poor service

Good day, I am writing to complain about what I have been told by one of your customer service agents by the name of Nari where she advised that I could never qualify or lend money from African bank. I explained to her that everything I apply I get a response that my account is with "AB LEGAL COLLECTIONS/IN ARREARS" however the account has been paid and why is it not being removed from the legal department. A proper rejection would be based on my credit score or affordability not receiving a response that AB LEGAL COLLECTIONS/IN ARREARS because this tells me that the account reflects as still active and in arrears when it should show that is closed. She could not assist me with this query and I would like this status to be removed as she also could not provide me with details as to when it was paid up on the system
