Don't know who it is, but they don't even leave a message

I am also getting numerous calls a day on my cell from this number. I called the number back on a private phone.  The msg stated they were conducting a survey for the CDC and to press 1 if I wanted to continue the survey.  I went on the CDC website and found that you have to be a "selected" participant and looks like some one sends you a brochure. They also said that a government employee would be conducting the survey. As I dont give out my cell #, I am wondering how the "gov't" got my cell #?  This could possibly be a scam trying to abstract personal id info. Surely a gov't employee would leave a msg, right? I would say BEWARE!

I let them go with their pitch and the questions were NOT based on Health in which I told him so, the man stated that "I know but I have to get this information before we can proceed further.  The questions were posed in which I believe is deceptive phishing methods, how many phones do you have, how many Land lines are there, how many cell phones do you have, is this a private residence?  I then told him that I was not available to continue the call.

I just received a call and they said they need to speak with the 2nd oldest male in the household. I said that was my son and he's sleeping right now and I won't wake him up. He asked when would be a better time and I said that my son was not going to want to do a survey. He said, very rudely, "Well, I would have to confirm that with him ma'am" to which I responded, in the same rude manner, "Well, I'm his mother and what I say goes". He then asked me, even more rudely, "Is he an adult ma'am?" At that I hung up the phone.

I receive calls from this number several times a week, all different times of the day.  Today I answered and just sat there for a while because there is usually no response to my several hello's.  Finally a man came on the line and said he, "was calling from the CDC... you know, the Center for Disease Control" ....(no, really?) He said, "my number was randomly chosen for a survey of health conditions in the gulf area."  I told him, no thank you, I'm not interested in participating and to take me off their list.  He then said, "but we would like the answers to our questions."  I said, well, I would like to be taken off your list.  He then wanted to know if he could call back later.  This is just a guess, but I bet they keep calling.  I'm wondering if filing a FTC complaint is a waste of time.
