Really Frustrated!!!!!!!

Premier Credit card department are unbelievable, I did an application for a limit increase 3 days ago, I have had no response what so ever from FNB, I am the one busy calling them getting no satisfactory results what so ever, I was told that the limit was approved, what I don't know is what is going on, I told them I needed the cash asap to sort out an urgent need, but no one seems to care. Instead getting help from my bank I have been with for more that 6 years, I am getting headache on top of the one I have already. I am really frustrated.
