Total scam. The IRS never initiates contact by phone or e-mail. Tax disputes are civil matters no police and no arrests take place. These people are little more than telephone or e-mail terrorists and should be dealt with as terrorists. They are located in India.
I just received a call from these scammer [***]. They pretending to be IRS agents. I began to grill them with questions. They put me on hold, then disconnected the call. Beware. Do not volunteer any information.
I got a message from a guy named Mark, he was claiming to be an IRS agent and he said that a warrant was issued against me. I called him and he said that he was going to " pull up my file". So i waited and he came back and told me what my phone number was. ( I am an accountant, so i know my stuff when it comes to dealing with the IRS) I asked him the most basic question regarding his IRS ID Number. Then he immediately disconnected.
