These scammers claiming to be the IRS called multiple times today and after doing research, I learned on the IRS.gov website that the IRS will NEVER call you to inform that they are filing a lawsuit against you. The IRS will attempt to inform you of your debt through a series of letters first. I called the number 213-479-6188 using a different phone and a guy with a thick Indian accent informed me that I was speaking with the IRS. His first mistake was answering my call immediately because in my experience, you can NEVER get to an IRS agent that quickly or easily on the phone (am I right?). His second mistake was that he informed me that he had already sent me two certified letters to inform me of the lawsuit....ok, he told me this without even knowing my name. At that point, I informed him that I was aware that this was a scam and to stop calling. I know things are tough in Cali....but common already!
