Debit order nightmare.

This is just a general note from frustration with the FNB system, when you enough money in your account for all your debit orders money comes off balance amount reflects correctly but because you transfer money into that account after a certain time 3 hours later it reverses the money even if you are not in the minus it is the most annoying thing in the world cause you charge me 105 rand and now I have to go and sort the payment out manually.
