Same here. I'm on DO NOT CALL LIST (worthless) and get call about "winning" a free cruise. Did not answer and did not "press 2 to be removed" from list.
Got call - did not answer - did not know the number - so I don't know if it was the IRS scam or the "free cruise" but it is annoying to keep getting call when you are on a DO NOT CALL LIST.
Your DO NOT CALL list means NOTHING to these people. They are calling from outside the USA, with faked )"spoofed") numbers. The only thing they want is your personal info and money. If you want callers like this blocked, go buy a call blocker device from your local electronics store, from Amazon or another similar source.
