I always get these calls when facebook reveals my number. They do it all the time on a regular basis, just arbitrarily change my privacy settings and my number is available to anyone who knows how to find it in my profile. I HATE THIS. I change the settings, contact to let them know, they always apologize, but they keep doing it. I don't know who this caller is, I didn't answer, I was too busy Googling the number to see who it is. But I do know that this call is totally unsolicited!
