I am sorry but there is nothing anyone can do here to help you with that. It's life, stuff happens and this is not the right forum to advise why specifically this has happened to you and what's the remedy. There are many factors that can affect quick turnaround of an application, even with priority processing.
The only solution is to wait for his passport. You could try contacting them via the paid helpline but that doesn't tell you much.
