FNB Credit - Confused and ***********

I was under debt review in 2017/2018 and my FNB credit card account was moved into a separate account. I met my obligations and have remained clear ever since, but I do know that there is still an amount to be settled in this account (which is now NOT listed as a credit card account under my name). Do you get it, FNB? I want to settle this, as it is still showing as "active" on my credit report. I have phoned the credit card department, who referred me to collections, who referred me to the debt review department, who referred me back to the credit card department! LITERALLY, I am going in circles! Does no one at FNB understand their own systems? It's simple: get me a statement, let me pay, and list my account as inactive with the Credit Bureau.
