On 8.6.2014 I received a call from this number, too. No caller ID. I did not answer and no message was left. Interestingly, I had recently been on the phone with Blue Cross/Blue Shield, as "scamfighter" stated the caller represented themselves, when spoken with.
Have received several calls from this number. Supposedly from wheaton, il. I had just spoke to blue cross blue shield and declined to take the survey after the call.
I received multiple calls from this number today. I do not answer calls if I don't recognize the number. No message was left. I, also, was on the phone with BCBS yesterday. Coincidence? I think not. I have now blocked them.
