I just received the same scam call and it was a recorded message, not even a so called human on the other end. They also threatened to send the "local cops".
It's funny and no insult to any culture every time I have been called it's always a person with a heavy foreign accent, are there no Americans that work for the IRS, since I owe 4,968.00! They are going to handcuff me in front of my house.
IRS Scam. Says that there are issues against your name and that if you don't call them back within 24 working hours, they'll call the local cops on you.
