I also got a call from this number. No message left either.

I also received a call from this number. I called back, and I got music???? Anyways, I also received a not-understandable voicemail full of static. >.<

Rec'ed call from that number, and spoke with lady who claimed to be from a University in Chicago doing a survey of children's health for the CDC.  I answered a lot of questions, but also asked a lot. She gave her supervisors number as 1-866-900-9601.  Also left the following number for more information  1-800-223-8118 which appears to be a CDC number.

i have recieved 2 calls from this number, around 7 pm two nights in a row.  I just called back, and they answered "Children's Health Study" or something, i just hung up

Person on other end claims to work for the CDC doing a random survey. The survey is about kids and cell phones.
I just told them I didn't have kids, and they ended the survey.

we also got a few missed calls from that same phone number 312-759-5255

I got two calls from this number within the past few days; no voicemail was left either time.

My phone number is unlisted, so how am I getting a call from someone I don't know? This is the second call in 3 days.

i keep getting this call, i don't answer, and no message left.......

Have been receiving several calls from this number. When I answered it I asked that they not call again, they still persist. Very annoying!

Two calls from this number this week so far, one was fairly late in the evening. No message was left. I'm on the Do Not Call list and rarely to never give this number out when registering for anything.

do not call

I too have had many calls from this number with no message left.  I finally picked it up and informed them that I am on the National Do not call List.  They argued that they were the CDC and could call me weather on the Do Not Call list or not.   I just filed a complaint the www.donotcall.gov.  I suggest everyone do the same.

How absolutely rude!  They called at 6 PM on a Sunday, the jerks, and I don't even have kids.  Calls like this are why we got rid of our home phone - we were paying for these idiots to call us.  If the CDC has to resort to buying phone nbr lists to get survey results, you'd think they'd at least filter it for people in their target group.

I have received 4 calls in the last 2 weeks from this number on my cell phone & I'm on the do not call list.

Keep calling me after I have said not to. Filed complaint with donotcall list already. Filing complaint with FTC as well. https://www.ftccomplaintassistant.gov/

This number is from someone doing a CDC survey.

I get one call per day from this number on my work blackberry! The other posted stated that this is call from the CDC. I seriously doubt that is from the CDC, I would not answer any questions from these people.

This number 312-759-5255 has been calling me. I find the many attempts to reach me disturbing and a waste of my time.
