Disappointing service

being a FNB client for almost 3 decades i must express my deepest disappointment with fnb,on 25 sep 2018 as i wanted to make a withdrawal in Johannesburg cbd,i realized like the ATM was compromised and immediately i transfered my funds from my personal Cheque account to the business account to avoid being a victim of *****,and later i transferred the funds,back into my cheque account and next business day i was shocked to learn that my debit orders were unsuccessful which is total nonsense the explanation is that there was no funds but the bank was able to the the R100 per debit order they charged me,from who? cause they say there was not enough funds.This affects my profile i seek rectification of all this.
