I feel the same, mam.
We sent them and email, to see if DS's app is in for this month or not.
I just remembered that I sent it priority with delivery confirmation. According to the post office confirmation, they would received it on Oct. 13th at 5pm. When I was sending it, I thought I have so much time, I guess I did not figured a post office holiday into the equation. LOL.
Maybe they just received so many last minute apps, that it takes some time to confirmed them via email. I am hoping...
