I didn't get to pick up the phone, however they left a voicemail stating an arrest warrant was issued against my name under USSN. Before they start the legal proceedings, they wanted for me to call them back and if I didn't or my lawyer my warrant will be activated. Then left me a file number of 26 Cfr.
I called the number 929-359-3533, got a voicemail with the following message: "this is the task force crime, division of the IRS, please leave a name and number and we will get back to you"
Don't be fooled or scared: IRS will never call you and certainly never leave you such "scary" detailed message or worst, allow you to leave a message on their so called voicemail.
Scammers, please be careful, DO NOT panic.
