yep, i've gotten these calls on my cell, too. i've gotten over 20 within the past week or so, and today they called me twice within an hour. i answered once, and replied that "she" was out, could i take a message, and then they just hung up. i answered it again today, and first asked who was calling, and they said University Finder. i asked if i could take a message, and they said, "no, i'll call back later," and hung up. i'm on cingular/at&t, so it's definitely not just for one company.
kinda creeps me out, though, that they keep calling...and at all hours of the day, too. the first one was after 9p, and for someone who doesn't know me, that's pretty late. i'm in college, as a lot of the people commenting on here seem to be, and there is just no time to deal with this!
