Unsolicited and unknown number called my cell phone. All of my home/cell numbers are on the DO NOT CALL registry. In addition, phone numbers are "unlisted" so how they obtained my number is not clear.
No messages or voicemails but it is annoying nevertheless.
I received a call from this # right after I filled out a free-bee thing on FB. It asks if you had the chance, would you go back to school? Of course, most of us are going to say yes and Bam - they got your #.
