Same, reported. Robo-call saying to, "Regard this as a final notice" of my IRS debt and that the IRS would be pursuing a lawsuit against me if I didn't call back right away.
Received a phone call from the "IRS" on 4/1 from a female with a foreign accent. She actually left a voicemail. Then on 4/2/2015, the same woman called me saying I had neglected to pay federal taxes from 2008 to 2013. She transferred me to her "boss", Mr. David Watson. He in turn had very broken english, telling me I owed 1000+ $$. I indicated there was no letter in the mail from the IRS indicating I owed this and was not going to rely on a phone call. He wanted to start filling out an affidavit. I questioned him on that. He started getting rude,telling me I owed money and that I would be arrested by the police. I told him I did not owe money and would not answer his questions. Oh, his employee number is 1993062.
