Called three times in a row, until I answered and said please stop calling (dinner time). Called back and when my husband answered, said it was Dept of Treasury and sending cops for me.

Scammer!  The Department of Treasury and IRS does not make initial contact by phone.  And, they speak English!!!

Said I have warrant for my arrest do to tax evasion. Told then to kiss my [***] an hung up

Just got 2 calls from a lady with a foreign accent about a pending legal action.  Advised me to retain a lawyer.  Scared me.  If you see her, knock her down for me.  My kid thinks the government is going to get me now.  

Same thing happened to me today. Lady wanted me go to Albertsons grocery store and get a Gov't voucher for what I don't know and that was going to be the only way the warrant would go away. She said I would be arrested within hrs. SCAM.....
