I've had a similar experience... I had sent in all my documents in November. I left a voicemail, sent an email, left my name and number with the receptionist, and have been calling every week. I never was able to reach the coordinator or get a reply. I understand they're busy with all the new students but I think they could find 2 mins in the past month. I got a similar email today saying I need my documents in by the end of the month or risk being bumped to the fall 2012 semester. I was pretty frustrated at this point so I started calling every 30 mins until I reached the coordinator. When I finally reached her I was very polite, and found out I was good for the feb 2012. However the attitude I got was unprofessional. The admissions person and interviewer were awesome. It feels like once AUA got my deposit checks they didn't need to be nice anymore. I really hope this is not a sign of what's to come.
