This was the message: Called from Woodville, MS number.

Call started by being asked if a specific individual (SI) would be at their home address in one hour to get served with court papers. When told no caller insisted we get pencil and paper to write down a case ID# and an 866 number. Caller said we needed to call that number back ASAP and threatened the SI would be held in contempt and face charges for missing court date if did not call this number. Caller was very info avoidant, would not give their name, company name or any information about who they were working for, just said they were "a process server." Caller would not say who the 866 number belonged to, after being repeatedly asked said it was "an authority" and when further pressed for WHAT authority they stalled, played dumb and eventually gave the name of a nearby city that we do not live in. Very sketchy bogus call.
