They left me voicemail saying that there a lawsuit against me when I answer they always hang up

Received a call from this number saying they were from the IRS and that they had a law suit for fraud. When responding  they hung up

I received a call from this number. I let it go to voicemail.  It is a computerized voice saying it is Officer Daniel Wideman calling you from the legal department of the internal revenue services.  It is in reference to criminal lawsuit filed against you. Your case number is CF93271.  The moment you receive this message, I need you to return the call.  The issue at hand is extremly time sensitive.  The Hotline to my desk is 202.840.6553.  I repeat is it 202.840.6553.  Don't disregard this emssage and return the call. Now if you don't return the call and I don't hear from your attorney either, then the only thing I can do is wish you good luck and the situation unfolds on you.
