I'm registered on the National Do Not Call List and this number called, and my smart phone showed the call as coming from Chicago, IL. An automated message said press 1 to talk to someone about a cruise, and 2 to be added to their do not call list. I pressed 1, and immediately started into a rant about how their call was illegal, I was on the National Do Not Call List and demanded to talk to their legal department. The gentleman on the other end said "**** you" and then I received a pre-recorded message that my number had been added to their DNC list. I called the number back and it said the number was unavailable.
