FNB decides how and when they want to put a hold on your card.

I am not sure how a director of his own company that banks with FNB is not allowed to be given information on his own business credit? However this also changes depending on who you talk to. The first 2 people and first 18 minutes of the phonecall, I was successfully verified and given information but they couldnt rectify the problem. They had to transfer me to a third person who refused to give me any information. The information I wanted was not sensitive, as FNB decided to put a hold on my card because it was over the limit? This is for a card that doesnt have a limit and we pre pay each month. This month was no different. I have been using the card the past few days but they decide to put a block on my card and when it gets declined embarrassingly for insufficient funds, which there is definitely not the case, they still wont uplift the hold. I dont have a reference number. Someone from FNB Card Collections, can just call me back.
