called on my cell phone but did not leave a message. this is the second cll I have received

2/5/08 - My daughter just received a call from this number - said it was CDC (Center for Disease Control).  She said it was a computerized call and hung up.  She also received a voicemail message (number unknown)yesterday.  The man did not speak very good English so it was hard to understand what he even said, but he had an 800 phone number to call back.

We are on the DO NOT CALL list.  Can they be reported?

This number called on a weekday evening and left a message asking me to return their call to participate in a survey to answer questions about the medications I may or may not give to my children (that I do not have).  I never returned the call, but have received calls from this number EVERY DAY SINCE...  going on 2 weeks.  Since the one message, they have not left another.

Just called by this number.  It was a computer calling my cell phone.  They said they were from CDC and performing a survey.  Left voice mail.  Said for me to call back for survey and will be paid $10.00.  Deleted message and filed complaint with donotcall.gov since I am registered.

I rec'd a message from a Disease Control center advising if I called back & gave the names and ages of my children & if they were immunized I would receive $10.for calling them back. The next day I had a missed call from this #312-759-2474, no message. I am on the do not call list. Why am I getting calls?
