keeps calling looking for Cindy.  No Cindy has ever lived here.  I do not know any Cindys. Will not stop calling.  I have had my phone number since 1978, so I am thinking that no one that is still alive has ever had it.

first my father received a call from Randall Young, I'm sure an alias, who promptly violated 3rd party disclosure laws to my father.  When I contacted him, I cited the FDCPA, and requested original substantiating documents of the alleged debt.  I explained that if he could substantiate the debt, I would happily address the matter.  He immediately became aggressive, stating that all he had was a settlement agreement for me to sign, which of course doesn't substantiate the debt unless I were to sign it.  After I explained that all calls on my phone are recorded, he promptly hung up.  It was easy enough to find the corporate office, so I sent a cease & desist via registered email (rpost.com) and fax explaining that I would be meeting with my father to determine if I would file a formal complaint with the AG of LA & GA, and that if I was contacted again prior to supplying substantiation of the debt as the FDCPA REQUIRES, that I would file a formal complaint with both AGs immediately...
within an hour, I received a letter from the corporate office:
Dear Mr. B
   We apologize for any inconvenience we have caused.  Upon your request, U.S. 1 Financial, LLC will no longer be in contact with you reagrding (CAQSE#XXXXXXXXX). We also advise you keep a copy of this letter for your own records."

UNSIGNED OF COURSE!  THIS COMPANY PURCHASES DEBT, BUT DEBT PURCHASERS RARELY ARE SUPPLIED WITH ANY SUBSTANTIATING DOCUMENTS OTHER THAN A SPREADSHEET OF ACCOUNTS.  NEVER AGREE TO ANYTHING FROM COCKROACHES LIKE THIS UNTIL THEY SUBSTANTIATE THE DEBT IN A WAY THAT WILL STAND UP IN COURT!!! YOU HAVE RIGHTS!!!

My parents received a call from Randall Young asking for my brothers phone number so they could get a credit reference for me.  I called him back and received his voicemail.  Told him my name and number and that I needed substantiating documents for whatever he is calling me about.  He returned my call, when I tried to talk he kept interrupting me so I said I just want to let you know you are being recorded and he said well, record this, you have trouble paying your debts AND HUNG UP!!!

A man called Randall Young called and said it was urgent that I call regarding a matter for LaVina Rodriguez.  I do not know who this LaVina is nor do I appreciate phone calls from Randall Young.   Take me off of your phone records please and do not call my number again!

What is there address and fax number?
