Who called from 6046082911

They said they were from Jack FM and were entering people into a "win at work" contest......

Yep that's what they said too.  96.9 FM and I ask how they got my number and they replied from a catalog.  I ask who was the publisher and they said we can not review that

It's legitimately Jack FM. I phoned them and they said they really are phoning people out of the blue for a promotion where you win prizes. Their goal is to get workplaces to play Jack FM as their background music, to increase their listenership.

Called on my cellphone.  I didn't recognize the ID, so I didn't answer, and they didn't leave a message.  Caller ID shows up as "PRIMUS TELCOM C".
