Caller ID said Zofia Oravec who said she was from IRS.  Lots of voices in background but we were disconnected.
Several calls recently from different numbers saying IRS.

They've just called me claiming to be IRS as well saying they "don't want me to go to jail."

Same as above.  Caller ID said Zofia Oravec who said he was from IRS.  Lots of voices in background.  Several calls recently from different numbers saying IRS had opened case against me.

Same here.  Lots of voices in background and she kept saying hello over and over. I hung up.

Yes, what a ridiculous conjob. Some dopey jerk with a [***] accent tells me I owe the IRS. Right, the IRS doesn't have an office, just Zofia Oravec.
Unfortunately I couldn't find my little digital recorder so I could record this fraud and sic the REAL IRS on him. If he calls back, he'll be wiping his butt with his turban in a detention center for the criminally insane.
