FNB *******ly removes money from account

We have 3 company business accounts with FNB. In the last 2 months, FNB has repeatedly blocked almost R100,000 from our account. They haven't given any notice to us. In the first instance, the funds were reversed within 48h as required by the tax act. The second time, no funds were returned (now 5 days after removal and the tax act only gives them 2 days). FNB doesn't respond to emails, ignores our attorneys, doesn't give any reasons for their behaviour. The relationship manager plays it down, the line manager doesn't bother to react in any way. I strongly recommend to never bank with FNB. Your money is not safe with them. Not only do they not bother informing their clients if they think that there might be a problem or notify a client if they were forced to remove funds from an account. They *******ly hold funds beyond the 2 day limit provided by law.
