FNB FREEZING ACCOUNTS

In my life I havent received such poor service from a bank whats the fuss about FNB! Absa never in their life closed or froze my account!!!!! October I swiped at a garage for petrol where i was told unsuccessful to find out my acc was frozen, my money????? Me and my son had to sit in the car for over two hours before i could make a plan for money to pay for my petrol. Just to go in to the bank about 3 times in one day for this fica validations just for my account to be frozen all over again when i need my money again my son had a fever of 40 deg i couldnt even pay for medicine...in my life i have never experienced such poor service just for fnb complaint dept to tell me today that the fica validations are closed over the weekend and no sympathy whatsoever that they can keep my money, i am a freaking single mom what in the life of me am i supposed to do i have no money, i am changing back to absa as we speak just proven FNB HAS HIS NUMBERS NOW doesnt care about the individual!!! I am so disgusted i promise you if by any chance my son comes anything over because if my inability to buy him something from the pharmacy for his fever this bank will be hearing from me for a long time
