Frustrated with FNB Building Loans

FNB building loans was supposed to do a final payout for my house developers. I have made Nokwazi aware a number of times that I need payments to be processed so that I can have access to my shelter. To my surprise, after I had authorised the payment yesterday, I find out, after calling the bank twice this morning that Thulani (who contacted me to authorise payment) had submitted an incorrect payment type which caused the payment to be rejected. Right now I do not have a shelter as the developer is not releasing keys for my property once he receives his payment. I've been incurring unplanned expenses for my furniture storage and accommodation due to the delays made by FNB in making this payment. I have been nagging and following up with Nokwazi since last week thursday (the 26th July) who kept on promising to update me on what is going on with the payment,but up to now no one has got back to me. Can someone please help and make sure that this payment is released before 1pm as I need to move in atleast today
