It's a phishing scam. I did some research online and the "free cruise ship" is a scam to get your email and bank account information. I recently bought ticketmaster tickets AND booked a room from hotel.com. I received emails from these guys with an address @roktpowered.com. One was
[email protected], the other was
[email protected].
This is all a scam. DO NOT give them your info. If they call, waste their time by making them think you'll claim the "free trip" and put them on hold for however long.
