Well Kneaded Massage/Selina Garrison No Return Calls / No Payment for Services Rendered/ Granada Hills, California

I was contacted by Well Kneaded Massage to provide chair massage at an employee health fair in Bakersfield, CA.  This was the second time I accepted an assignment from them -- the first time I was paid.  This first event was 10/13/10 and the second was 10/25/10.  To this date, I have not received any payment, and I cannot get a return call.  I have all the confirmation e-mails from Selina Garrison, who stated the terms and the rate of pay.  I have been providing massage therapy for three years and have never received a bounced check or anything negative from any clients.  I'm amazed that Selina Garrison is as unprofessional as she appears to be.  I am also checking into legal recourse against Selina Garrison and Well Kneaded Massage, Inc.
