This is an illegal IRS scam phone call. I work in the telemarketing industry. I called this number that the automated message gave me, just to play around a little..
first off, they start off giving their fake name, fake badge ID number and then tell you YOUR CASE ID #. Keep in mind at this point i have not given them my name, information or even my real telephone number so clearly something is wrong with that..
I continued to play along with it, and after i asked him what the case was for, he said if you dont want to listen you can wait for the lawsuit in court(still dont know what about) and you can [***] and [***] off..
