FNB frozen accounts unnecessarily

Business account opened more than two weeks ago, activated already and transacted on the account. Now just as I am about to receive payments the account gets frozen with a further document request for documents that I have already sent. Now as payments are coming in customers cant add the recipient and others from other banks are sending proof of payments to an account that is frozen. FNB is a mess, no contact with the customer to let the customer know whats going on, they just leave you hanging with the standard 3 working days to get back to you nonsense. No thanks, ill take my business elsewhere
