IRS scam! Robot voice says to call them immediately or IRS will sue me. Say I owe thousands of dollars. Extortion. Very threatening. If I owe IRS taxes and they claim to be the IRS, why don't they know my name? Plus the number they call is my work phone number. The IRS does not have that number...plus, IRS sends letters out, not threatening phone calls. Major scam!!!
When you have time call them back over and over and say nothing. I have blasted them 20 times or more. Great fun and wastes their corrupt time. You can do this with all scammers.
