A lady which didn't give her name or company states there has be some fraud against phone number, bank account and social
want me return call to solve the matter

I received the same message. Pretending to be from some law firm. Hung Up because I knew it was a scam.

Received a phone call from 770 648 2931 She stated she is from legal litigation and she said this is against Maricopa County and me. Stated that it had to do about SS number... SCAM...

This is a SCAM. They pretend to be professional and state it is regarding litigation and SS#...HMMM ...what are they after?

Received several phone calls, recorded introduction stating they were needing to talk to me about fraud, and asked me to press #1, then it hung up.  I tried to return call, no answer.  After receiving several of these, I finally called back and it was answered.  The lady knew my name, perhaps from the phone ID, and stated that they were investigating a claim regarding an unpaid loan, and stated it was about to be served in court. I told her I had no knowledge of this, and she asked alot of questions, and told me I should have received some correspondence about it and had my mailing address.  I have not, and have no knowledge of this, and told her.  She told me good luck in court. I thanked her.  I am sure this is a scam.  She talked so fast that I couldn't understand any details, she couldn't give me any names, or to whom this loan was supposedly made from, etc.
