These people at "ESG Research" or "Political Opinions of America" who are making these illegal telemarketing robocalls are not taking a real survey. That's part of their scam -- an attempt to get around the do not call list by using a fake survey. They are spoofing dozens of different phone numbers from all over the country.
The first fake company was ripping off a couple of real companies with similar-sounding names. The second fake company now has a fake website.
If you press any number (or fill in a form on their fake website) to have yourself removed from their calling list, you are only confirming that your number is real, etc.
The cruise is not free. You will have to give them a credit card to 'hold' your reservation. They will charge 'small fees' to it. However, the fees are not small and are NOT refundable. Some people who have fallen for this scam have also had to sit through interminable time-share presentations with high-pressure salespeople. Come on!
Hang up. Block the number if you have that capability, or add the number to your phone's address book under SCAM. Immediately report each scam call that you receive to www.donotcall.gov. If they don't know about it, they cannot do anything about it.
