Clearing of funds on business account

We recently opened a business account with Standard Bank and we received money with the New Zealand Ambassy and we were told that the money needs to be cleared by providing the necessary documents to prove where the money comes from and we did just that.

We have been waiting for the funds to be cleared for almost a month now, we have sent numerous emails with no response and we have a project that we deliverables up on, we are being delayed. This is the kind of incompetency that is totally unacceptable. This is really ****es us off.
