I received two voicemail messages about a serious federal criminal matter, need to call 415-746-6086 so they can help me before a federal magistrate judge. Clearly a scam. .   .   .   I hate getting unwanted calls. These two messages filled my voicemail box. Very annoying.

I keep getting calls from this number - it's a sxam.

Also in Michigan. 2 calls from a Georgia phone number (678-608-3557) in less than 2 hours
I am in deep trouble with a Federal Magistrate, and I should call them immediately  at 415-746-6086.
This loser is now on my blocked call list.

In-laws received call from this number.  With their limited English, they thought that they heard that their daughter was in trouble or in an accident.  I told them to not give out any information.  A neighbor of theirs called the number and discovered and confirmed than it was a scam.

Received 2 calls within minutes of each other basically the same story as everyone else - I had to call immediately regarding an "enforcement action" by the US Treasury.  Person identified themselves as Steve Mafin and had an accent.
