FNB..... About to loose yet another long service customer

Absaloutly frustrated with this Bank. On the 27to do a debit order reversal and to block off that debit order frtom going threw in future. I'm a health care worker and with this epidemic we facing for me to take that day off was nearly impossible. Hence my reason to blocking future debit orders from that company. The consultant was helpful and of cause to block and reverse, comes with a charge which I gladly excepted so I don't make anymore trips to the bank. Obviously this was followed up with on their side, be July the debit order went off again. I emailed and called Numerous times which is a waste of time and money because the service is suspended via the FNB app, they refuse to help you over the telephone. Eventually when I did get threw to a agent, the call is dropped down while I'm explaining my situation. I want this corrected. I paid for a service.... For absolutely nothing. I'm really frustrated!!!!!
