Answered phone was told it was Adelphi University.  Not buying

I have been getting multiple calls a week from this number and once again on a Sunday.  I called back the number and it went straight to voice mail indicating that mailbox belonging to 'Adelphi University Annual Fund' was full.  Sketchy to say the least.

Ive been getting the same phone number calling me everyday for the past few days.

This number has been calling my fiancee for about 3 weeks.  They'd always call after 8:00pm, one time calling on a Sunday.  Tonight I picked up, and they asked for my fiancee by name.  I merely asked them what kind of a university employee works after 8:00pm on a weeknight during a blizzard.  The woman "Cassandra" then thanked me for my time and hung up.  Scam.  Do not entertain these people.

Called my DNC registered cell on 07/01/14 @ 6:19 PM. I didn't go to Adelphi University. I don't pick up callers I don't know and have blocked this number whether is real or a scam.
