Claimed to be from some sort of firm, couldn't quite make out which one or what the guy's name was. The guy who called seemed to know my first name but claimed to be looking for a man I'd never even heard of. I told them they had the wrong number and he hung up. Later he called again (how professional). I sent it straight to voicemail since I was working and didn't want to waste my time with him. He left a voicemail for the guy he had been trying to reach (a Mr. Kaiser Booker) about a "legal notice" and went on about how Mr. Booker had received a criminal complaint against his name, social security, and drivers license. Against my better nature I called the idiot back and told him he had gotten it wrong again, and he immediately hung up on me. His number is now blocked.
