This one is great.
They call saying that you are a great credit card payer and you are entitled to 0% APR on all of your credit cards.
I informed the caller that my number is on the do not call list, and I would report that number. The guy on the other line then said: "shut up then". When you call the number back, it goes to a disconnected verizon subscriber.
No trickery here going on at all.
