Who called from 5167340886

Did not answer. angry that they called my cell phone.

Scam robocall from foreign sounding "Kevin Mason" referencing United States Treasury and an enforcement action, second warning, magistrate court, etc. Apparent scammer/fraud call.

I got the same call on my supposedly 'unlisted' land line number. Sounded American, but the message left was very choppy and difficult to understand. Same name, message as you mentioned in your post, Katy.

Got a call from this number at 7am this morning, saying he was calling about an enforcement action on behalf of the US Treasury.  I just hung up.

I don't answer numbers that I don't recognize, so I'm going to assume this is a scam like everyone before me has indicated.  My CID says Plandome Manor, NY.
