Call them and ask what's going on. I've said it 100 times during this and the last application cycle, and I'll keep saying it. Don't be shy about calling admissions offices to ask about your status! As long as you aren't disrespectful or neurotic (e.g. calling them at regular intervals), it is not going to hurt you. If anything it could help--maybe they didn't get something required from you due to the postal service or maybe they just misplaced something. Often times, they don't bother to contact you about it, they just mark your application incomplete and move on. Of course it's too late to fix it now, but perhaps it will unearth something interesting. Sometimes calling to check your app status will spur the school into thinking you're interested. I know one student for example who called to ask about their waitlist and asked if they could come to the second look because the school was their first choice. Lo' and behold, they ended up at the second look AND bumped up on the waitlist.
Also, if you're going to post things about admissions offices, please say which school you're referring to. Others may be in the same boat wondering what's going on.
