They called me and didn't leave a message. I returned the call and heard a voice mail with a southern man voice, he sounded like a pedophile. I think he diddles boys.

Don't bother answering.  Just keep their number on your caller ID and report them to authorities.  No need to pay one of those sites for more info, just stop them in their tracks since they're obviously up to no good

Called me just now, said that they are organizing firefighter show and asked for money
