Call Center QA They did not pay me for work that was done Boston Massachusetts

I have not received payment for work that was completed.  The company initially looked to be a good match.  They are looking for people to make mystery calls from home.  Process was automated and I received the work almost immediately.  At first I thought it was a good company.  Lisa Williams sent me an email that payment was being made via paypal.  Which was fine.  The next day I thought something was funny because I normally receive an email from paypal saying that money was received.  I never received the email and I never received the payment for work that was done. 

I have attempted to call the company (left a voice mail) and no one has called me back.  I have emailed Lisa numerous times and have yet to receive a reply.  I even went onto their website and sent a message through their message board.  Again, no reply and no payment.   I have also filed a complaint with the BBB and will next be filing a complaint with the Massachussetts Labor Board
