FNB WORST

Last month i was able to reverse debit order of R300 via FNB APP!!! After helo peter they magically "unlocked" debit order that was unauthorizlly debited!!! FNB CALL CENTRE CLAIMING THEY CANNOT REVERSE IT AS ITS LOCKED BY COMPANY! *** is wrong with FNB!! FNB allows unauthorized debit orders to go off my account. Funny enough FEW MONTHS AGO when 1st debit order was done R200! HOW CAN AN AUTHORIZED DEBIT ORDER MANDATE CHANGE THE DEBIT AMOUNTS!!????? If it was the direct debit amount should be fixed???!!! I managed to reverse charge via banking app,sneaky as the company's are THIS MONTH, the amount was R300 Bare in mind I HAVE STOPPED THE DEBIT ORDER BUT MANAGED TO DEBIT AGAIN, I have been calling the entire day! all they do is put me on hold, until you eventually hung up due to airtime running out what the hell, FNB HAS SYSTEM ISSUES FOR 3WEEKS NOW!!! I have tried emailing NO LUCK It seems like FNB had a share in these companies, because either way they ALWAYS benefit from this *****. Why is the bank not doing anything HELP CLIENTS, Why don't they put an authentication system to ensure that I authorize all debit orders that go off my account? Why are there fees in place when unauthorized debit orders get unpaid? WHY IS THERE A CAP TO THE AMOUNT OF MONEY I CAN DISPUTE, I SHOULD BE ABLE TO REVERSE ANY UNAUTHORIZED DEBIT ORDERS WITHOUT ISSUES, FNB ONLY BANK THAT CAPS DEBIT ORDER DISPUTES UTTER BULL****OTHER BANKS REVERSE ALL DISPUTES THEIR CUSTOMERS HAVE!!!
