FNB *****ing money

On Saturday I transferred money to my credit card. When I wanted to use my credit card it said I have reached my daily limit although I wasn't close to it. while tapping to try and make payments I get a declined message every time but not knowing that the money is actually going of my account. Talking to FNB yesterday and today they are aware of the issue, yet I need to contact them to hear what is going on. Empty promises are made every time and I am sitting without money in my credit card..... FNB why are you *****ing my money?
