I got a call from this number at 9am today. I called it back and an Indian guy answered saying he was from the IRS and asked me for my phone number. When I gave it to him he knew my name and then proceeded to read a long and official sounding document that he needed to send to my attorney. He threatened jail and fines. Soon after he finished reading this I told him I don't make [***] for money and never owe taxes. Then he hung up.
