I called this number back and found out it is for Kaplan University, where I am a student at. It is the document control center. They were not calling to solicit or anything like that, they were calling because of my financial aid application.

Got this call as well, more than once. We have the telezapper so we don't answer the toll free calls, so of course they didn't leave a message.

I just got a call from the same number and when I picked up, the person on the other line just hung up.  I got calls from this number four times this week.  I wish there was a way to block this call.

don't know who or what they want.   Never leave a message and I have not been able to answer the phone to ask them what they want.
