Claimed to be from the IRS and they were filing a lawsuit against me

Got a message from this number indicating that it is from the IRS.  Thje message states the IRS is filing a lawsuit against me.  Returned the call and the person did not identified himself. The gentleman pretended he was looking for information in the computer.  Asked for my name again and responded that I will be arrested.  When I tried to get additional information the man just hang up.

Received message from robot with suggestion to call back.
Very suspicious.

Receiving calls from this number saying that they are they IRS.  When I called back and asked them to prove that they are who they say they are they hung up the phone.  They are claiming that they are going to Audit me and if i pay a certain amount it will all go away.  They need to be stopped!!!

I just got the same call as Sam claiming to be the IRS and that the IRS was filing a lawsuit against me and I need to call back right away. I blocked them
