Christine Johnson called and said that they had sent 3 certified letters and had sent a federal agent to my home.  They didn't know that they were talking to my sister.  She was tipped off when they used my maiden name and I have been married for 15 years.  They wanted her lawyer's name.  She told them it was Clarence Darrow.  They said that they would contact Mr. Darrow.  Good Luck with that.  My sister then called the woman a lying [***] and she responded in like and then hung up.   About 15 minutes later, Christopher Paul (Badge #5592) same phone number, this time asked for my mom. My sister asked for the husband's name.  He said Paul.  My sister told him, Clarence Darrow was their lawyer.  Then asked to speak to a supervisor.  Christine Johnson came on the line, recognized my sister's voice and hung up on her.
