NO CUSTOMER SERVICE

I am so disappointed with FNB and the problem with reversing debit orders! I have been trying to reverse an unauthorised debit order for the past 6 days and every day you are told to phone later and eventually tomorrow...I understand system errors accur, but a whole wee**** In the meantime I do not have money and need to put food on the table. This is unacceptable as there is no communication to FNB users. Calling their call centre and be placed on hold for more than 30 minutes only for your queries not to be resolved is very wrong. How long will it take for the systems to be resolved so that they can assist us?
