Unfairly Charged a fee for Excess Items when there was money in my account

<p>Hello Peter, I made about 3 purchases on my FNB Business Account on the 24th March while there was money in my account to cover these items, then on the 25th normal account charges went through as usual, then my account went into Debit, then only on the 28th the retailers did their banking and the 3 items started appearing on my statement. 29th March I then got punished R465 for these 3 items that went through while there was originally money in my account. Now on my statement it shows as if I made these transactions after the account was in Debit caused by Monthly Bank Charges. I called Business Desk and the lady was not helpful at all, it sounded like I understand her work better than her. FNB Ref: ReferenceRp ********** 5573</p>
