REFUND AND STOP CHARGING ME FOR TRANSACTION WITHOUT FUNDS.

FNB has become a ******** and *****ing corporate organisation. This bank has allowing transaction to go through without funds and will debit my accounts for all the amounts end of the month without any extra changes for this transaction in my count for years till last month when i saw 90.00 appeared on my transaction, i called them and found out the told me the changes where for purchase without funds, today i saw close to 500,00 again listed as to be debited end of the month, i have a very long relationship with this bank and 90% of my salary goes to the credit i am paying to them. i just found how bad this bank can be and will only advise to stay away or monitor your transaction, this bank is full of ********** and do anything to take your money.
