Who called from 3122014623

Norc U Chicago calls every week.  There's millions of other people they can ocntact, but they are very persistent. They've called me about 15 times so far and tried to conduct a survey asking for my children's names and birthdate.  Sounds like they're phishing for information.

And they call on Sundays and odd evening hours. I don't know what they want as I never answer and they never leave message.

this is legit:  http://www.norc.org/nis/faq.htm

called at 9:00 on Sunday Night just to hang up without saying a word.
This is creepy,why do they keep calling?
STALKERS!Leave me ALONE!
