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:
http://news.uscourts.gov/warning-arrest-warrant-scam

"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."

If you KNOW you owe no money, or believe the call was from a fake debt collector, please take the time to read this:

he gave my parents the case number 115555-42

A "case number" given over the phone means nothing.  It is merely a scare tactic.
Read the information in my original post here!

If it happens that you DO owe money, keep reading ...

A phone call from a supposed debt collector is not legally sufficient evidence of debt.

The Fair Debt Collection Practices Act (FDCPA) includes statements such as this:

* Every collector must send you a written “validation notice” telling you how much money you owe within five days after they first contact you. This notice also must include the name of the creditor to whom you owe the money, and how to proceed if you don’t think you owe the money.   ["Written" means snailmailed ... not emailed or texted]

Therefore, if that caller wants you to pay immediately, before you get the written validation notice via snailmail, or if the caller wants payment via green dot, Western Union, or other untraceable means, then the call is definitely not legitimate.

IF you wish to communicate with the supposed collector / creditor, visit  the following page, for example "Action Letters" to snailmail:

i thought so thanks for the information

They called and it came up as 0000000000 so I sent it to voicemail. They left a message saying that I had a "formal complaint filed against you at my firm" and instructed me to call 8663518630. I have gotten phoney calls like this before so I was about to stop listening when a computer generated voice said my first and last name. It really freaked me out.

I had a "formal complaint filed against you at my firm" and instructed me to call 8663518630.

They have called me several times over the past few days leave a message for Kelly Gritton (my ex-husband of over 20 years second wife) I have not spoke to either of them since my son turned 18 6 years ago.  I called them back told them to remove my # twice now they just hang up on me
