Called and left no voice message.

called, left no message

Asked for credit card info - said I would have to pay them ($19.99) to stop calling.  Nice try... I've reported it.

These people call form different numbers all of the time and never leave messages. I called back and it's a debt collector.  Now that I know, I will answer and tell them I owe them nothing.

It's a waste to talk to scammers, and calling back can verify your number and result in more calls. Don't answer unknown numbers and BLOCK if no message is left.
