State Investigation Department Rose Johnson, Senior Affidavit Processor stating a lawsuit filed in my name for doing some fraud and criminal activities regarding some cash advance. Internet

I received an email with my correct phone and ssn but the address was incorrect from a Rose Johnson to my work email address stating that she was trying to reach me regarding a very serious matter about a lawsuit filed on my name stating that I was doing fraud and criminal activities. 

She also stated that I was going to be legally prosecuted in court in a couple of days and that my ssn is put on hold by the US govt. and this was the final notice  and that US cash advance is seeking to proceed against the fullest extent permissible by current federal banking law.  She gave me a case file number and the callback number listed with extention.

I tried calling the number but kept getting a message stating that "we're sorry, the number can not be completed as dialed, please check the number and try again."
