Legitimate process servers do not call to warn you, or to get money from you to stop the process. They will deliver the notification without warning.
Also, if you were threatened with an "arrest warrant" via a phone call or email, read this:

"The warrant is phony. A valid warrant would not be served by fax or e-mail. It would be served in person by a U.S. Marshal or other law enforcement officer."
"Anyone receiving a fake arrest warrant should contact the FBI or the district U.S. Marshals Office. If there is any question regarding the authenticity of a warrant, contact your district clerk of court."
Phone call was received on Thursday, September 4, 2014. Woman on the other end was looking for one of my relatives. She said it was a legal matter. I asked her to call back and leave a message on my voice mail because I didn't have a pen on me. She never called back. I then called her and got a message saying the number is an invalid number.
I got the call, regarding a so called complaint with the sheriff I hung up. Very creepy guy yelling at me telling me to get a pen and paper. DONT ANSWER!
