Called my home & didn't leave a message. I called it back & got a recording saying that if I wanted to be put on the no call list dial 1 Then said I was put on the no call list & would take 48hrs to go in effect.
What probably really happened was that by calling back and pressing 1 (or anything; even just by calling back) you got your number on the sucker list that will now be shared with other scammers.
Please don't answer unknown numbers and never call back.
