also got call no message left

Got a call this evening, but no message.

got a call about an hour ago from this number, no message left.  when i called it back i got a recording saying "we have been trying to reach you regarding your carnival cruise" or something like that..then it gave an option to stop them from calling me..

Got a call from this number about 1.5 hours ago about a Carnival Cruise, hit 1 and it connected me to someone who said my name was drawn to receive a cruise and only have to pay the taxes.  Anyone know anything about this?  Is it for real or a hoax?

Recieved the call a minute ago.  Talked about winning a cruise. Then said Press 1 for Operator 2 to added to do not call list.  I pressed 2 but wish I would have just hung up
