You are refering to "NRA GROUP LLC. d/b/a NATIONAL RECOVERY AGENCY LLC"  http://www.nragroup.com/contact.html  
not NRA, LLC, who is in Southern, FL.

Has called twice in two days.  They however believe they have someone elses phone number.  When I called back they stated they are NRA LLC, a pre-litigation firm.  When I typed their name into google they are a debt collection agency who are not affiliated with the BBB and have complaints on Ripoffreport.com
They stated that "the opportunity to resolve your claim/allegations is closing"  When talking witht the operator I asked what NRA meant and she stated they are just initials of the owner of the company and that they are based in South Florida.  But, in previous web searches, I have come accross them being in PA.  So there is oddly something fishy going on.
