I am tired of FNB

I logged a complaint and a Premier banking consultant called me regarding my double debit order that went off my account. The consultant went into my account and could see that I had a double debit order which went off on the same day, told me she will send the information to the administator to reverse the debit order. I was never given a reason why they cannot reverse my debit order immediatel, I followed up this morning to see how far they were with my complaint, another consultant is now telling me that it will take 5 days to resolve. What is so difficult to return my money into my account that I never authorized Standard bank to debit twice? How do I even trust that unathorised debit orders won't go off on money that will be deposited into my account this week. I have given FNB enough time to resolve this issue as stated by the email I received from the ombudsman and will be taking this further. I need my money reversed into my account by the end of today so that I can close my accounts with you.
