Got the same call from "Niki Johnson" when i called back they read me a supposed document stating i had committed tax fraud and was being charged with criminal tax evasions charges and would be arrested within an hour if i did not pay what i owed. When i asked questions they hung up, but called back threatening to have me arrested if i didn't pay when i asked them to verify their info he got very angry and accused me of having an attitude and kept insisting if i didnt pay i would lose all my properties, possessions, accounts and my driver's license would be suspended and i would serve up 7yrs in federal prison. Long story short i blocked the number onmy reject call list.
Just got a voice mail from this number. An automated woman's voice said she was from IRS and I had to call back without delay to avoid further penalties. Then she said take care! What a joke. .
