Just received the same Robo call. Stated that IRS was filling law suit and to call # immediately. Here's a link to IRS website with notice about these scams. https://www.irs.gov/uac/Newsroom/IRS-Reiterat ... -Telephone-Scam
I did call back and they gave a very old address. I told the Indian guy I was calling my lawyer and he said he was going to transfer me to the supervisor. The supervisor also sounded Indian... He told me to go to the bank and I told him it was closed lol Then he asked me to go to "the Walmart" and he asked for my current zip code... I told him I was gonna call back and he told me I couldn't hang up. After yhat he was like I can't hear you I'm calling you right away... And he did... Afterwards I found out the second number was a real IRS 18008291040. Be on the look out.
