United Public Opinion Group Scam, Internet

This company called my cell phone sounding reputable and offering 2 free cruise tickets in exchange for answering 10 survey questions.  They represent themselves as a public interest polling group.  The questions do not ask for a credit card or social security number, just your age group and level of education.  The message then directs you to a website, www.surveycruise.com. 

I went to the website, put in my email address (so they now have that too), and received a confirmation number.  Supposedly a travel representative will call me in 3 days.  I did an online search and discovered this is a scam--that they use this to send you lots of spam or to try to give you the hard sell on an upgraded package, with nothing free.  So I dialed the number from which their call was placed and got a porn message.

I know, shame on me for hoping there's such a thing as a free lunch.  But I have to ask, isn't there anyone policing this kind of thing?  This is the second time this year that someone has tried to scam me.  I feel as if these people are given free rein to do whatever they want at our expense.  This country really blows.  Really, it's okay for them to call me from a porn number?
