I missed an application deadline, but it wasn't entirely my fault. How can I still be considered? About a week ago, I went to submit the application for the mathematics PhD program at one of my top choice schools.  The form told me I had missed the deadline, which was December 15th.  I had January 5th written down on my list of application information, but when I looked it was indeed Dec. 15 on the department website.

I distinctly remembered seeing Jan. 5th, however, so I looked it up again and found the website for general graduate admissions where I found the deadline to begin with.  It said/says January 5th, and is even program specific (under the "PhD in Mathematics").  So I emailed my application to the mathematics department graduate admissions email address explaining there was an incorrect deadline on another part of the website, provided a link, and requested that I still be considered.

I haven't heard back from them aside from an automated "we'll get to this eventually" email, and it has been about 7 days now.  I think I have a strong application for this school in particular and really don't want to lose my chance to apply.  What do I do?  Should I try to call the math department?  Submit it to a different email?  Or am I just boned?

EDIT: I should note that this is a big school which will probably get a lot of applications, so hopefully they haven't gotten far through review yet.  Also, everything except my personal statement was on the website before the Dec 15 deadline, but of course the submit button was not hit so I don't know if this helps.
I would try and personally contact someone at the school, like @gerrit commented, call them. Try and explain your situation, and say that you hope you will still be considered for the program. Do mention that it was not that you simply forgot the deadline, but that an official document stated the wrong date and include this piece of evidence. Stress that you are very enthusiastic about the program, and that you would be disappointed if this communication error would prevent you from having a chance to enter the program.
