They are calling me too and left a message that I would be deported to my country of origin- born in Texas. Lol- whatever!!!

I got a call from this number. A weirdo spoke with fake accent claiming that he is from IRS. These jokers never stop until trying to get someone fall into their tricks.

I got the same call several times. Guy with a heavy eastern accent, says He's from the IRS. is name was Derrick May, but I'll bet it was the same guy. Had a similar call from an African-American male saying there was a grievance filed against my company and that I had to call back to settle or else it would go to collections. This guy called 5 times before the calls stopped.
What's with these rash of calls! We tried to call local PD but they were not interested.

I received the exact same message just a few minutes back and it was the same person. This is the third time he is calling. I did not answer the phone and he left a voicemail.

1) The IRS doesn't call people.
2) Don't even entertain these call. Call them back can backfire.
3) Report the calls to the FTC and the FCC.

I got a call from this number saying he was calling from IRS and that "a warrant had been issued because there was a serious error in my tax return" . There is no error in my tax return and the IRS does not issue warrants for errors. He asked that I call back at the same number and talk to Mr Mark Brown. I scared him by telling him that I had called the police when he had called me earlier and left a similar message, and they were tracking where he was calling from and would soon be there. I did call the number, the same person, with a strong accent answered, but he probably recognized my voice and did not talk further.
