This was the VM I got. Of course it freaked me out and of course I had to look up the number before I called back. Glad I did. Because there was no first attempt.

"Requesting your serious attention ignoring this will be a second attempt to avoid initial appearance before a magistrate judge for a federal criminal offense the number to reach us is 614-335-9187 I repeat 614-335-9187 advise you to cooperate with us to help us to help you thank you…”

It is best you never give any unknown caller personal information including your name.  Probably nothing will happen but it is best to not engage any conversation with them except to get facts as to whether they are legitimate.  Anytime you feel uneasy or the caller gets abusive end the call.  Thank you for posting here so that others can make informed decisions as to answer the phone or ignore the call.  Good luck with school!

IRS scam

I received the same message everyone else did above. It went to my work phone which is very odd. I don't trust it and don't plan on calling back. Thanks for the thread!

They will call from various numbers and is often the same group.  I had one call that told me to call another number then that number called me asking me to call another number.
