FNB is full of shift

So at FNB decides to select which items to reversed the money, Since July the 05 i have been charged unpaid items, like now just woke up to another charged of items paids no funds, really @fnb? so my account will always be on a minus because even if i have R70 available balance the following day it will on a minu, @FNB please get your house in order my account doesnt have a overdraft facility, because i cannot make a purchase or withdraw if there is insufficient funds, why am i being charged here? its not like its a debit order bouncing. i am leaving this bank for good this time i am sick and tired of this exploitive bank nonsense, **** YOU FNB
