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.
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.
