The caller stated that I will be served legal documents pertaining to a cash advance from splash cash.  I am yo give them money from a prepaid debit card to stop the garnishment and to stop the server from serving me

Don't give them anything.  This is  a scam.  Nobody is going to serve you documents.   Only judges can issue garnishments and that only after a hearing where you would be given a chance to be heard.  

Report this to local police and attorney general.

See:  https://www.consumer.ftc.gov/articles/0149-debt-collection

Complete scam.  No one gets a heads up they'll be served - the process server just shows up, unannounced.  If you had an unpaid loan, you would also have gotten dunning letters via USPS mail.  Any caller who asks or pressures you to pay immediately - and especially with prepaid debit cards - should be considered a scammer.  BTW, garnishment cannot take place unless you've been served, gone to court, LOST your case and then a judgment entered against you.

Follow the steps in what you need to know. A legitimate debt collector agency should not have a problem with giving you a real business name and address you can google and verify via google street view, BBB etc.
For extortion Scam Operations, file reports with the FBI, your state attorney general and Department Of Justice,FTC & FCC..

And folks should consider looking at maybe getting call blocking device or phone....you can Google them and many are around $60 or so.

Keep getting calls (the number called from is 209-416-0803), one right after the other, some show the number, some show "no caller ID".  They have left two messages.  Each message stated The exact same thing word for word. Her name was "Debra White" and she was calling from the Department of Legal Services that they had a court summons (from the county that I live in)  that was scheduled to be served on me from a "local courier" and that I needed two forms of ID so I can "sign documents over to myself" and that if I wanted to put a stop order on the service then I needed to call their corporate office (they have given me TWO different numbers for their corporate office 401-390-2150 and 209-416-0803).  Seriously, I am sick and tired of scammers.  Never fail, at least every 3-4 months its something different.  They have also started harrassing a family member, I'm not even sure how they got their number, I haven't lived with this family member for over 30 years and have never put them down as a reference of any sort. These a***oles just don't stop. I don't owe anyone any money, but apparently my info has been sold over and over after applying for something online over 5 years ago. I have checked my credit and nothing shows up.  If anyone gets a call like this DON'T GIVE THEM YOUR INFO. ITS A SCAM.  By the way, process servers don't call to make sure you are home or tell you to be home at a certain time to get served, just FYI. If it was a legitimate company that you owe money to, they will correspond with you through mail and they have to give you an opportunity to dispute it.  They just don't start calling out of the blue and say they are going to serve you legal papers.  BEWARE PEOPLE - PROTECT YOURSELVES AND YOUR PERSONAL INFORMATION.

Said she was div. 1 courier,serving me good luck, good day, I am notifying state attorney general and law enforcement,
