Those "IRS" calls - have been receiving them for over a year. Yelled at couple of them. They keep calling on your home and cell - I wish I knew who's selling our numbers to those criminals! Have a suspicion that mine getting sold by Verizone: this BS started as soon as I changed my old Internet/phone provider!
Person called several times and left me a voice mail. Stating that a warrant was sent to the police department for my arrest. I replied that if i were being called for IRS issues that I would wait for a notice in the mail. They did not like my response and hung up. I suspect I will not get another call from them.\
