Yeah, DH is right. Get to Admissions right away. Preferably in person so they know you mean business. In my experience colleges don't want to help you at all, so you have to get on their case about it. Call them every day and make sure that YOUR issue is being addressed accordinly. Don't let up, these people don't give a damn about you unless you make them. So lay it on thick and give them a guilt trip.
Good luck.
