Can Branch remove me from deployment orders(wheels up in 3 days) to PCS?

I was told under no cirstances i was getting out of this PCS move to Alaska.Im suppose to leave in 3 days to go down range(a little late for a PCS you think!!!!!) My gear is already in country. What do i do and what can i do. I already tried deletion of orders and maybe an extention. Branch shot it down
