Fake "IRS is filing a law suit against you" scam

Have already rec'd this call 2 times this morning, it's only 10:30.

IRS is filing law suite scam. Automated phone call.

I have gotten the same phone call twice  as well,  these people just do not give up.
First of  all the irs does not make phone calls, to personal homes , they contact you through letters,  they do not even ask for anyone, they just say the irs is  filing a lawsuit against you, ,   if they can not get you to respond this way, they try another way, which they already did last week,

Two calls today alone. I call the number back and asked why they keep calling my number. They immediately hung up. I have now blocked the number. Why be on a registry when it does not work?
