FNB still Refuses to explain why my bank account was frozen for 3 days while I was on holiday!

FNB froze my bank account for 3 days while I was stuck almost 2,000km away from home. To this day the only explanation they keep on repeating is "*****". FNB refuses to explain what kind of ***** and who made the decision to freeze my account on a Friday afternoon. I was left penniless for 3 days and my Wesbank Debit order was declined all because of the incompetence of FNB ***** Department. This is my last request for an explanation - failing which I will be forced to escalate this matter to the Banking Ombudsman in my quest to find answers.
