FNB freezes accounts for no apparent reason and opening a business account with them is a big mistake

This bank is by far the most wicked institution on this planet. Since last year they froze my account with my money inside thousands and they have since not advised why they blocked it nor did they release my funds. That's crazy it's like a **** bank they are full of lies. I kept calling then from department to department but till now my business account remains restricted and my money frozen inside the bank. For what reason? I don't know they won't tell me since last year. Be very wise when looking for a bank especially business accounts these wicked people will rip out your business and crush your funds
