Leaving FNB and its high charges

After so many years banking with FNB and being so commited to them when people advised me to leave it and seeng many family and friends taking their money to other banks,FNB has finaly given me a reason to move my money and salary to other better banks that charge reasonably So my pay date changed and i had debit orders bouncing and to my suprise in a week time my account is on nagetive R1500+ I mean how rediculouse is that,for a bank that claims to help you do better with money and that claims to take care of money for our future and families,that amount would by my family groceries.Now I wonder if by the time money goes in to my acc i will be at -R20.000? I will spread the word an be one of many South Africans who will sure to never ever advise anyone to bank with FNB.I have banked with them for years now its time to find a bank that will give me value,security and respect my money
