Said they were an attorney's office looking for a name that matched that of a distant cousin. Also said there was a complaint against him, a civil complaint and that I needed to have him contact them right away. Sounds like a scammer or debt collector.

They called me to tell me about a legal complaint against a person I've never heard of, and said I was part of the complaint....and I've never even been to the state where their "office" is located. I don't know how to report these people to the authorities to end their threatening calls, so if you know how please do.

We cannot make any reports for you.

Here are two pages of links to (mostly government) sites in Canada and the USA were you can report phone scams, or learn more about them.
