I received 3 calls from this number saying they are the IRS. I don't believe the IRS would call people who they think have cheated or committed fraud. Besides they called on my cellphone and I only give that number out to a select few.
Do not answer calls you don't know and never call them back. The IRS will not call you. The IRS won't ask you to pay in i-Tunes cards. The IRS will not wish you "good luck as the situation unfolds". Trust yourself and your instincts - do not let a bully intimidate you by threats that are nothing but hot air.
I received a call from this number claiming to be the "IRS". I was so upset because a few yrs ago i was a victim of id theft so i started asking the person for their "IRS" ID number she refused to give it to me so i started yelling and insulting her and daring her to admit she was a theft and a scammer, and she said yes i am and there is nothing you can do about it.
