Robocall IRS scan where they state the IRS is suing you. Blocked!

Gotten two calls from this number.  Robo call but the message is cut off, all I heard was there is a case file i need to call about.

The claim the IRS has filed suit against me. But I have not received any mail or anything from the IRS since last tax season. I called the IRS and they have no record of any suit being filed against me clearly a scam.
