FNB is messing with credit scores

On the 14th of December went into the ottery Branch to pay outstanding fees and close business account with my business partner. The lady at FNB checked and went somewhere, came back and said account is already closed. There is an outstanding amount however we don’t need to pay. Only once we want to reopen the account they might request a fee. Both my business partner and I was told this. On the 27th of December I received a sms that I am handed over to the attorneys. I was called on the 3rd of Jan by the attorney for the outstanding amount. I haven’t received any documentation, nor email regarding this matter. I told him what FNB personnel told us which he advise I should talk to that bank again as this will definitely impact my credit score and that the account is not closed until payment have been done, which I also will get the choice if I want account close or not. FNB personal just say I must contact the attorneys as it’s no longer in their hands. I’ve been with FNB since I start to work however my trust is gone.
