Are they on leave too?

I feel like I'm been pushed about by both MOE and NIE. I only wanted to do a simple thing called applying leave, and NIE asked me to call any 1 of the 2 officers at MOE. I called and this guy asked me to apply leave from NIE. And when I asked the officers at NIE, they asked me to email the first of the 2 persons stated from MOE. I emailed her and called her on Wed and today but there is still no reply. If my leave is just next Wed, I'm not sure if they can approve in time within this short period if they drag on like this. I hope they reply soon, and I can't help but feel unhappy about it.
