Panda Research / lies, deciet,failure to pay

Is there any recourse ?? I asked for my money back in March 2009 and got a verifaction f=phone call eventually and still have not received my money.. They did answer my email and said no one was home... Not true I have caller ID and no who calls at all times. I believe they just don't want to pay?
Does anyone have a way to get them to pay and if not who can we contact, official etc to turn them in for keeping our money
