robocall left a message saying the IRS is filing a lawsuit against me and I needed to call back immediately

I received a phone call with a recorded message from 786-738-7895 saying I was being audited by the IRS. Immediately after the recorded message I received a live call from 863-840-3852 saying I am being sued by the IRS - file is in Washington DC and a warrant for my arrest has been issued. Amount owed for 2009-2013 tax years is $8281.00 due to a miscalculation in section 101,  and I can make a partial payment of $500 today.  People on phone (call was transferred) were Officer Eric Brown badge GS5801 and Officer Shawn Marshall - IRS has agents, not officers.  Both men had Indian or Arab accents.

I just got two robo calls.  I went to call back and it just rings.  So annoying.  I get too many stupid calls daily where people think I am a sucker.

Received a call from IRS saying I was being audited by the IRS.  Such a scam people should find something better to do instead of trying to get a buck for nothing!  So freakkkin irritated..

IRS SPAM.
Also calling from 863-840-3852.
DO NOT CALL BACK.
