I got the same message about IRS trying to reach me and "it" asked me to call back. I am thinking, if it is the "true" IRS, they need to send me a lettle instead of letting a machine to call me.
I received a call from 234 308 5230/234 308 5030 saying IRS is filing a lawsuit against me. Scared the hell out of me. i did not call the number they told me to, but I redialed the number that they called FROM. Not in service. Was I phished/hacked or were they trying?
