Msg says "IRS has filed lawsuit against you"

Received 2 identical robo calls this week- one from Burbank, CA, 818-281-9357, and the other from 646-712-9714, New York, NY.  Both recordings claimed to be a final notice from the IRS. Reported and blocked both.

Automated message saying that I should call them back. Bums.

Supposedly the "IRS" scheduling my court case.. IRS scam

I received 2 calls yesterday saying that it was the IRS.  My understanding is that the IRS does not make these calls and I want the probable scammer to stop.  I do not owe the IRS!
