Who called from 3125787017

Called twice on my cell while I was at work - no message. I don't care who it is, 2 or more calls + no message = number blocked

Yes, it's legitimately the UChicago--NORC on behalf of CDC, conducting a survey about childhood immunizations.
I called back based on the reports here. Since there are no minor children in the home, I wasn't eligible for the survey. Caller/responder was very polite.

Caller claimed to be from the CDC -- smelled like a fishing scam to get personal info.

My girl friend keeps getting calls from this number.  She doesn't recognize it

this number has me 12 times
