Frozen Bank Account

After my business accounts had been frozen for 5 weeks in February and March this year, despite my supplying all necessary documents, I wrote a report to Hellopeter. Within a short time the accounts were unfrozen. Now one of the accounts, a money market account containing a fair amount of cash, has been refrozen. When I phoned FNB Business Banking yesterday, I was told that all correct documents had been received but that the account still had to be reviewed by the QC (?) department. No-one could explain why the account had been re-frozen. I have laid an official complaint with the complaints dept. of the bank who have promised to escalate the matter. In the meantime I have no access to my funds and next week is the end of the month when many payments are due. How FNB can continue to treat their long-standing customers with such arrogance and incompetence, is beyond my comprehension.
