Maverick AMC (AKA Nationwide AMC) Matt Moore Appraisal Management Company won't pay their Appraisers Newtown, Pennsylvania

I was hired to complete two appraisals for Nationwide AMC back in August 2010.  They have yet to pay me.  I am owed $850.  My calls go unanswered, and when I was finally able to track down their accountant, Dep, he confirmed that they indeed did receive payment for the appraisals from the borrowers, but that the funds were used to pay other unpaid bills.  WHAT???  I am in business to make a living and be able to pay my bills too.  I am mad at myself for letting this happen, but I will continue to try and get my money.  Nothing makes me angrier than not getting paid.  And nothing motivates me more than unresponsive dead beats.  Shame on Matt Moore.  How would he feel if someone didn't pay him for his services?  I'm sure his family and neighbors would be shocked to learn of his behavior.  Then again, maybe not.
