This number doesn't stop calling me until I give in - then they told me that I have an IRS lawsuit in my Federal Income Year 2016 that I needed to pay! Just to be legit they gave me File case number and a website IRS.gov - luckily its my day off and I'm on my computer typing everything he said such as IRS Laws section blah...blah...that if I will not pay they will arrest me. He's really persistent that I will believe him but I know the Laws, I study Laws, I know my Rights and I'm a law abiding citizen - then told him that the number his using is blocked in nomorobo and some websites. Well - after he hears it...that's the end of it he didn't say goodbye or warned me, he just hanged up! BE AWARE! KNOW YOUR RIGHTS! LAWS KNOWLEDGE IS A PLUS!
