Who called from 3012233004

Just got this call obvious scam. I didn't call it back. Federal government wouldn't call if there was fraud they would show up in person

Has to be a scam.

"Intending your serious attention. Ignoring this will be an intentional second attempt to avoid initial appearance before a magistrate judge or a grand jury for a federal criminal offense. This is the final attempt to reach you. To resolve this issue immediately and to speak to a federal agent, the department's callback number is 301-223-3004. I repeat 301-223-3004. Thank you."

Same message on my machine.  I tried to call back to mess with them but would not go through and then it would be busy.

just got a call same as the others   first of all never got a first call  this is a scam
