Have gotten several calls, telling me a sheriff or process server will be coming out to serve papers UNLESS of course, I call 1-844-236-4226 and give them a "file" number, and of course some personal information.

BE CAREFUL of this scam!   It's the new "identity theft".   You will be forced to give personal information and then harassed.

Do what others do, when they call to tell you the sheriff or server is coming out, ask them to pick up a box of donuts on the way.  Or, you may ask the caller for any other "service" you'd like...
