Who called from 2062012078

Same. Left a message on my landline answering machine that the IRS was suing me. Lol. At least they made me chuckle. I think the IRS has bigger fish to fry than me.

Same as above. A machine generated voice left message saying " Final notice,  If you don't respond the IRS is going to sue you. Call....".

Same thing. Left message saying IRS was suing. No taxes are owed, more importantly this would be sent certified mail. DEFINITELY thinking a scam.

Same thing - wife just called me to say we got a call from this number saying the IRS was suing us.

It is an overseas scam that has made the news.
