They called me from a restricted number looking for my father who I havn't heard from in months and left to be homeless in california :( anyways they said it was for Michael Stafford in regards to a civil complaint and gave me a case number to give to my father if I ever hear from him. They have also called my mom and left several messages. My guess it's either bogus or an old debt someone bought and is trying to collect on.

Same exact experience. They have contacted  4! of my family members, claiming that they are alternative contact numbers for me. Giving a case reference number too. Saying that documents have been sent to addresses of mine and returned unsigned. Who are these people is right! Here is the information they left me.
Superior Document Services
TIMOTHY CARTER
for DC & Assoc
told me to call 626-269-9056

Two different individuals, a woman in English and a man, called me on my cel phone as well as 2 of my family members. The call was from an another state by a company called Superior Legal Documents Services. They claimed to be searching for me about a civil lawsuit against me. They left me two messages demanding that I call them back to provide them with an address where I must receive the notification to appear.  I googled their phone number, and this so called company did not pop up in any of my searches in cyberspace.  I called a paralegal friend, and she said that when she called them, they behaved hesistant,  and they would not give her a straight answer about who she could speak to about her client(me)! Who are these people?!?!?!
