Problem scheduling 72-621, any idea's?

I've been on the phone with Prometric and Microsoft for the past hour trying to schedule the 072-621 academic exam, and the rep at Prometric tells me that it don't exist. He searched for it under 070-621 as well, and said there was nothing. You're not able to schedule academic exams on their website, so this is my only resort. Does anyone know what might be going on??
On this website it clearly states the exam number and the academic exam number:

For example, I want to reschedule my 291. I can either go the 29th and 30th of January, or the 4th, 5th, or 6th of February. Those are my options for the next two months. They only allow you to book eight weeks in advance too. I'm going to have to start watching Prometric closer than the Cisco gear I'm bidding on.
I wish I could help you out. They don't even have any of the 072 exams as an option for me. What does MS say?
