this guy leaves 'official notice' threatening criminal charges, or arrest at my place of employment on voice mail.
thing is, I'm retired on social security

Left a message that he was State Process Server  and that the call was my notice of an official court summons. What a joke these people are. I guess there are enough people who would be fooled by this scam and give them credit card money over the phone or they wouldn't be able to get away with this for as long as they have been doing it.

these guys are a scam.  they get mad and really unprofessional and threaten to find your address and hurt you when you call them blocked or unknown back.  :-)  DONT GIVE THEM ANYTHING> FAKE FAKE FAKE> SCAMMERS!!!! He tried to tell me he was standing next to a cop for his protection.  (WE ARE ON THE PHONE FOR ONE, LOL, WHAT PROTECTION?)  I told him my first name was chris and he asked chris what, i told him middle initial P. and he said last name, so i told him Chicken. lol.  What a fool.  Hope they get a life sooner or later.  

Be careful don't give any information to this dude he is scamming so many people. .Called me wanting money saying I was going to prison if I didn't pay him..The thing was he already had some very personal information. .

These people are scammers that are making up FAKE debts and then trying to terrify you into giving them money. Do not let them scare you into telling them anything and DON'T give them a single penny. Someone actually had the gall to call my co-workers and my job and lie and claim that they had a summons for me and that they were "prosecutors". I blocked my number and called them back, it's some guy's (Brian Cranston/Ryan Cranston?) voicemail and he claims he's a "mediator". This is an obvious scam. I don't know how they're getting information about people. I mean, calling my co-worker's cell phones? WHAT?

Call your local law enforcement and file a police report, go to fraud.org and file a complaint, then go to the FTC and file a complaint there. If you don't believe me that it's a scam, call the person/company that they claim you owe the debt to and ask them.
