i got a call today from the same exact number.  the man identified himself as  Mr. Lancaster from Pre-Trial Processing claiming there were two "allegations" filed against me and one was a felony. i called back and was cut disconnected twice, when i called back the third time an extremely rude woman answered the phone saying, "what do you want? i just connected you to him?" Flag!  She looked up my "case number" and said i owed American Airlines $4300.  I said i knew nothing of this debt and would need verification.  her reply?  "are you gonna pay or what?"  I said no i don't know about this debt.  she then said, "oh, don't give me that" and hung up.
this is fraud and illegal and next level scamming.  don't fall for it by giving them your money.  the proper way to collect a debt is to send notice via USPS mail and then the calls start.
infuriating and was very unsettling when i first heard that message.

left message to call back

I received a creepy call from this number.

Litigation Services called and left message saying I was being sued. I called back and no one answered so I left a message.  Next morning I get a call from them, Brian Philips said I was being sued by Citibank for $18,000.  I said that the statutes of limitation had run out on anything I had in 2009 so I don't owe them anything. He tried to tell me I was wrong, I told him I knew the law and I'd see them in court.  In 2009 I lost my major income from my IRA in the market crash and consulted a attorney at the time. In my state anyone that wants to sue has 4 years after that they can't.  HELLO it is  2015 and  2 years past the limit.

Litigation Services called said I had a debt 2010.  Asked me to pay settlement on the phone via credit card or checking account.  I refused...told them to email me proof...never got an email.  Called back...said I didn't get an email...They still have not emailed me anythig.  Could be a scam trying to get money!
