It's a robocall irs  scam.called 4 times today

Received a phone call twice, supposedly from IRS saying its their final notice and they'll file a lawsuit. Call came from 636-812-6320. Asked me to call back at that same number.

I received five calls within 24 hours. Definitely an IRS scam.

Very annoying constant calling several times.
I feel bad for the elderly or those who don't know better that may get this call.
They should be arrested, we have no right to privacy!
