I got a message on my cell phone stating the IRS is filing a lawsuit against me and to call back at that number, I know the IRS doesn't make phone calls first they send mail

received message from this number stating had to call to get report number for law suit against me from irs lady"s voice

Received multiple messages from this number stating the IRS was suing me and I could find out more info by calling back this number.

same thing.  I tried to call back just to see what was on the other end.  Lots of background noise.  Some lady answered and I told her I was returning a voice mail.  I couldn't hear anything else she was saying.  Then it got disconnected lol.  If this was for real, I'd expect a formal letter to be sent to me first.  IRS has my address lol

Received robo call from this number saying it was my final notice from the IRS.
