Who called from 3123798010

I have been getting them as well at the house and on my cell. I do not have a total account

keeps calling my cell and will not say who they r

Someone calls and ask for someone, and when asked what this pertaining to, they just hang up.

Keep getting calls from 312-379-8010.  Want it to stop. My cell phone # is private.  Sick of companies selling our cell phone numbers, wasting our daytime minutes.  This should be illegal.  Do we have NO privacy anymore in the U.S.?

They called me and asked to verify who i was before they could tell me who they were. I believe they are trying to see if someone will give up their personal information. Just hang up when they won't tell you who they are.
