I too just got the " Investigator Nicki Johnson" phone call too. I just blocked them on my iPhone, but I wonder how many elderly people fall for this! Sad world we live in...here I am legitimately working like a chump, while these guys make $14 million a year with scams!
I have received two different calls, one from robo Nikki Johnson with the IRS, no one answered when i called back, from a blocked #!!! Lololol!! The second was a threating one like the post a few before me, also telling me not to interrupt(and with thick accent) i got heated when they threatened my job,my kids, and jail time, but as soon as i said mail me the charges, that was the last time they called me. We all work too hard for our $, dont be a victim, call these scammers out and make them get real jobs!!
my mom received a message- woman identified herself as nikki Johnson- an irs attorney. told my mom her or her attorney had to contact her as this was time sensitive and needed to talk to her before irs took action. total scam
