Pathetic service

I Opened a new account for Business - A client paid me to buy stock to complete installation at the client offices.

FNB has now blocked my account/, Placed account on hold to to FICa regulations and to confirm legitimacy off transaction. I need to send through supporting document to confirm legitimacy of the transaction and source of funds. I have suppliers to pay, stock to buy and wages to pay but cannot transact on the account due to account placed on hold. It takes 3 to 5 days for fnb to verify transaction etc.

How do I operate the business if the account is placed on hold and have to wait so many days to get the issue resolved. I have a deadline with my client and now cannot perform any payment to my suppliers and cannot pay wages to my staff members tomorrow.
