This is a attorney collection agency in Santa Ana, CA. called The Moore Law Group.
They will call and start recording you without getting permission first. They called me recently so I know their tactics. These are attorneys so they should know better. But collection attorneys are from the bottom of the barrel anyway so you can't expect much professionalism from these kinds. They called from 714-431-2000. I would just not answer their call or pick up and hang up right away so they can't even leave a message.

They called my cell number asking for someone that I didn't know.  When I first answered he said his name and that he was from the Moore Law Group on a recorded line.  Seemed to be polite enough.  They weren't looking for me so.....

This is a collection agency/law group.  They call themselves Moore Law Group.  They are very aggressive.  Do not talk to them on the phone unless you do not have a means to pay the "alleged debt".  These calls will not stop unless you pick up the phone but remain silent!  Register them in your phone or get caller ID!  Fight back by not talking to them!!!!!!!   This wastes their time!!  If you get a legal letter in the mail, make sure that you do not have any money in the bank for them to confiscate!  They will eventually get the message.  If you decide to settle the debt with them, you will be slapped by the IRS and charged a capital gain.  Get the book "Debt Cures" by Kevin T.  from amazon ASAP!!!!!   You do not have to play this phoney debt game in this fiat (fake) banking global scandal!!!!!!!!!!!

This is Moore Law Group.  These people will not stop calling.  It has been over 6 years since I owned a credit card.  I just answer without saying anything.  I make sure that their time is wasted.  However, I will not let them leave a message.  One of these days, they will get the message!!

I feel sorry for you.  I have been receiving their calls, but it is for my ex girlfrien who decided that after ruining my life, I had to go.  Well, for me, it is so bitter sweet, actually awesome!  She took everything I had, my job, my house, my pets, my stuff, my money and left me for dead.  It is nice to know what she is about to get!
