Home Remedy Group Fraud that takes your money and vanishes Newport Beach California

I responded to a letter that indicated the possibility of a lowered monthly payment with my current mortgage company. The reduction rate was from 5.5% to 3.25%. Karl Stordahl was the first contact I encountered.  He explained what I needed to submit to the Home Remedy Group to begin the process of a loan modification.  After all information was submitted to the Processing Department (Dennis Serna, Lisa Kilgore, Aron Parks, Myra Borello) Mr Strodahl informed me of the necessary fee to process, underwrite and finalize the modification.  He stated the fee was due before the underwriting of the loan could be completed.  I arranged for five payments, four payments of $1,000.00 each and one payment of $995.00 to be automatically withdrawn from my checking accounts. I received three phone call from Mr. Serna to update me on the development of the case. On November 4^th, I contacted Mr. Serna, but  the line was not working. I then proceeded to send emails and have not received a reply.  I have kept all documents related to this terrible scam and I am anxious to know how to proceed to undo the financial damage done to me in this already stressful situation.
