IRS SCAM..... said they were with the Audit Department - Mark Wilson ID 3256621(sounded like a woman) - I asked her what service center she was with... I confused her - she first said California then Texas / but didn't know what a service center was.... when I asked for their address... they gave me the Waco TX address of the Internal Revenue Service... when I asked whose attention to mail it to.  She hung up on me.
