"The UPMC Depression Prevention Program seeks men and women, ages 18 to 60, to participate in a research study examining the effectiveness of an FDA-approved antidepressant for major depression. If interested, call Traci Salopek at 412-624-4444." - this is what I found when searching for this number. The above number called my cell phone.

I said "Hello" and hey hung up.

Called my cell phone three consecutive times without leaving a voicemail.  I picked it up on the third call (was trying to sleep after working night shift), they asked for someone I don't know.  Told the caller wrong number and hung up.

University of Pittsburgh looking for donation.

Got a call Sunday morning at 10:30 a.m. Who makes sales calls on Sunday mornings? Didn't answer. Didn't leave a message.
