Thank you friends for you advice...
I did talk to the Dean of Admissions yesterday (politely) about the situation. Basically, she said that she didn't know what happened and that the committee would review my app ASAP.
Needless to say, I got notification of my acceptance today via email.
(I know this doesn't exactly fit the forum, but I thought I should let you all know since you gave me the advice.)
(They're still bastards though.)
