Exploitation by FNB, they will do anything to make money! ** STAY AWAY FROM THIS BANK!

I have been charged R330 in fees for purchases i did on the 18 May which reflects as #ITEM PAID NO FUNDS 3 ITEMS ON 18/05/. When I called the call centre they said my account is not in the negative and the merchant banked the transactions on the 23 May. My 3 transactions was a total of under R100 and furthermore the money was deducted from my balance. This is total exploitation by fnb as this a new charges I never experienced before. What makes me more angry is that I got charge 330 for transactions less than 100. I would advise all to stay away from fnb and rather go to capitec, I already have an account with them and they don't pull these gimmicks. I will be moving all my accounts over because this is ridiculous.
