have gotten numerous calls from 312-2733-9104, the don't leaave message.
I am filing a complaint fcc.gov, we will see if it stops.

here is the liink for the fcc,  http://www.fcc.gov/complaints

Got a call during lunch from this number. It was an automated woman's voice saying that if I answered the survey on national debt, I'd win a cruise to the Bahamas for two. Obviously this is a scam, but I answered the survey anyway. The woman's automated voice then told me "You will now be connected to a travel agent to reserve your cruise to the Bahamas". Then I was connected to a man who congratulated me and asked for my name.. I hung up. SCAM! probably wanted my credit card info or some other.

just got a call from this number, i called back and the recording said that it was for the survey that is expired and gave me an option of not participating in the future once.

I didn't answer the call. No message was left.

I'm also amazed by how much this number is calling people currently. Just got this call at about 3:00 EST, didn't answer, no message.
