Claims i will be sued by the IRS

I got  a call saying that I was gonna be sued from the irs then I lost contact . SoI returned the call. Some guy answered telling me F#!@ you.

Same think happened to me. I called back and they quickly answered. I've never had a government agency pickup on the second ring

I keep getting these calls, they call repeatedly, if I don't answer. I called them back. It was a mexican man. He answered, IRS. I said, bullish.. you call me again, and I will report your [***] to police, for telephonic harassment,  understand? He said, yes maam.

And IRS, doesn't answer, saying, IRS. They call themselves by their name. Full, not abbreviated.
