'You have won a cruise" scam. Second call in two days.

Those that are fooled by the "free cruise" scammers, will be left waiting at the dock for a ship that never comes, while the scammers sail away with their credit card information!

These damn scam losers with their travel survey garbage nonsense.

how do we get off their list of  victims?

Unless you have fallen for their scam you're not actually a "victim", but a person being pestered by these lowlifes.You can report the number as an abuser of the do not call list, but seeing as all the numbers they use are spoofed, the results of doing so may, or may not help. It's usually best not to answers calls from any numbers you're not familiar with, especially calls unidentified, or from out of your local area.
