DJR Group LLC Hydra Financial I got scammed Internet

I was initially contacted by a company called West Star Holdings Service saying I had taken a loan out about two years ago and closed my bank account to stop paying the loan.  They in turn called an arbitrator which is west star holdings to handle the case.  When the arbitrator called me they said a warrant had been issued for my arrest due to bank fraud.  At the time it sounded legit, so stupid me asked them what I had to do to stop the warrant.  They informed me that they would settle on three hundred dollars and the warrant would be withdrawn, well I was scared and gave them all my info and they got three hundred from me. This was at the end of June 2015.  Now fast forward to July 13th, and I get another call from a company called Litigation services, basically saying the samething, except they would not tell me the original company.  The person I talked to was very rude and when I tried to ask questions he hung up on me.  I called him back and wanted to know how much I owed to stop the warrant, and this time it was over one thousand dollars.  I asked him what I had to do to settle this and once again he was rude and in a hurry and at the end of our conversation he said he would stop the warrant but I had to send the funds.  I hung up and said I would call him back.  I called the Illinois State's Attorney and they directed me to the Attorney Generals office.  I talked to them and they told me it was definetly a scam, and they knew about many scams similar to this.  I did not or could not find anything online about west star holdings service, but as far as DJR Group LLC the initial company with the first incident, there are many reports about similar scams from this company. I have not been able to find anything online about Litigation Services.  I got duped the first time but the second time I was more aware of what was going on.
