I just received the same call and they left a message stating they were the IRS and were filing a law suit against me and I need to call them back at the same Number. No Way!!!!
I called them back and told them they were scamming pieces of $h!t and a couple other politically incorrect phrases. I am now blocked by the number, lol. I reported it as well, not a bad idea for everyone to do that, include the number, maybe the can catch the sob's
I also just received a call from this number stating it was the IRS and it's a final call and that there was a lawsuit being brought against me. I just added them to my auto-reject phone list.
Called at 6:45AM, left robocall message giving me final notice that IRS is filing a lawsuit against me and to call the number back for more information. I've blocked this number.
