Unhappy FNB Client

I am having the worst experience with FNB at the moment as i still don't have funds in my account. i had a savings account linked to my normal day to day account which i have finds in. i had to place a 15 day notice period for the money to be paid out and after waiting the whole 15 work,king day period, I'm still told that the money has been release but it hasn't reflected in my "available balance". I need this money urgently and the branch manager couldn't assist me as he stated that its system delay however the money will reflect within a week. I don't have a week, I need the funds urgently for a purposeful family project!!! As a loyal fnb client, I expect better service than this and i need someone to contact me so they can resolve this issue. I am tired of the endless trips to the branch that don't seem to give me a resolution.
