Usa Legal Resource Keeps calling - very rude staff Nationwide

Got several calls from this office reporting on my voicemail that either I had called them or someone referred me.

I called the company back asking who they were and if they know who referred me.  The male who answered was very rude and said "How should I know".  I asked him if he had any record of how or who and he again said "why are you asking me this, I don't know".  I said "you don't have to give an attitude, I was just asking you a question".  He got loud and said "You don't give me attituide".  Wow.  I was simply wondering if someone had referred me and why?  Apparently they did not like that. I hung up on him.  He called me back twice and let it go to voice mail, he left no voice mail.  I then called back to get a supervisor and the same man answered so i just put the phone on mute and let him sit there.  He said "hi loser don't you have anything better to do with your time".  I sat there just listening to him then he started laughing and sat in silence for a good minute hung up.

Nice professional company.  I DO NOT recommend anyone deal with these people.  All I wanted to know is where they got my number?  Who's the real loser in this case?
