One of those calls Clark Howard says to hang up on. Indian accented man said he was from the US Department of Treasury IRS and a warrant had been issued for my arrest for tax evasion from 2012 in the amount of 3000.00. I told him I needed to call him back, he said I could not call him back and that if I hung up since the call was being recorded I would be arrested.  I told him if he is going to make fraudulent calls from a government agency, he should first warn the person that the call is being recorded, I told him I would call my local office and to get off my phone. there was a lot of noise in the back ground, Clark Howard says these people are scammers, do not pay them, the irs will not call you. they will send you a certified letter even if you have a P.O. Box.
