I have received several calls on my answering machine (starting in mid 2008) from this man saying he is special investigator James Arcadie and then the SAME guy saying he is special investigator Mackenzie Johnson.  Tries to sound very intimidating.  Says there is a civil complaint against me in my county.   He says I must call him or I will be taken to court.
I've called my county court and they said the case number does not even match the numbering system they use for cases.  It's a scam.  
Also calls from 312-265-7830
