I get a call just about every day, except for Sundays, around 8:30 AM, sometimes a little earlier, from 1-718-874-0973.  They have never left a recorded message.  When I try to call the number back, I get a recorded message saying that the number is not or no longer in service.

Trolls were beeping in while I was on another call. I ignored it because I did not recognize the number. No message left. Furthermore, I have never even heard of collegebound.net. I've been out of grad school for over 10 years now -- and I never give out my phone number.
