He called me too.. asking abt my details for which i said I will send the details by mail to the college. I suspected some thing

I am getting calls from this numbers from past few days but every single time, I was busy so could not answer it...I called back on the number but nobody answered it...Nobody leaves any message but since I am a graduate from USF, I recognized the number that it is coming from USF...But it comes between 6:30 and 7pm daily...

same thing...only one ring then hang up same timeframe

called and hung up around 6:30

This is USF calling. The purpose of the calls is to reconnect with alumni and parents of students attending the University.  I worked there when i was in college.  Money raised helps finance many scholarships, fellowships, chairs, professorships, and many other important things the university. Whether or not you make a donation, remember that the callers are current students just trying to do something for USF.  Be patient with them.  Personally, I used to not mind giving them a donation, and I had already shelled out a ton of money as an out of state student!
