Fake IRS call. Caller told me that I would arrested if I did not call Ross Taylor , the Chief Investigator back . They said I committed Tax Fraud and sent money to my "home country" Iraq since 2008. They said I had been "tracked" for several years and that the police would come to my door if I did not respond today...to the Investigator. There was the sound of other phone operators in the background during this conversation.  I am not Iraqi , have no ties to Iraq and was born in the USA. When I called the number back (from the caller ID) the man apologized immediately and said "I bow my head to you. Please forgive me. We are looking for another person , same name etc...but different phone number". Then HE abruptly said "and don't call this number again". I said "don't call my number ever again" and hung up. I want to report this...but don't know who to call.
