Nedbank adversely affecting my business

I had to go to Nedbank to re - FICA my businness account this week which I did on 27th of March. Now today, the Nedbank FICA department has frozen my account even though the branch I did the FICA at has confirmed all the documentation I submitted was received and correct. I have to pay my staff today and there is a lot of other month end transacting that I have to do! I have called the branch and they apologised profusely as usual but have not yet fixed the problem. I also cannot receive payments from my customers as the account is completely frozen for no reason that I am aware of.
