United Public Opinion Group took marketing info in exchange for a cruise and directed to website to retrieve tickets. that was a dead end. Internet

I was called for an automated market research survey and promised two cruise tickets if i answered the questions.  I answered the questions and then was directed to their website and told to logon with my name and phone number.  I did as instructed, but that resulted in a dead end. 

That is, when I entered the information I was told it was invalid.  When I went to their "contact" page and entered information, an error page returned.  There is no phone or street address on their website.  When I called the number that called me for the original survey it was busy.  This appears to be fraud.
