These [***] called and a recorded message said "That is not a valid option" and hung up. I called back and asked who they were looking for. I was told by a woman that she didn't know who she was looking for but that I have a warrant out for my arrest from the National treasury? I laughed & said "Nice try!" Smh. It makes me want to disconnect my home phone.

Get a call blocker so the fraudster can't call you again with this number.
You can also block entire area codes.

Rec'd voice mail yesterday 21 Sep and today 22 Sep regarding the US Treasury identifying me in a pending financial fraud suit.  Good luck!
Call used the name David (something), couldn't understand the last name.  Caller was a middle easterner with a heavy accent.  Said I needed to call them back before it goes to Fed Court...

Yep, same middle-eastern scammer as noted by others, left message on answering machine, claiming I had Financial Fraud with U.S. Treasury, and to call them back.

This is the same call I got awhile back. Whoever is doing this, is scamming us!
