This thread freaks me out, as I have one of their CAIs on order right now. I'll just let it go and see for myself I guess, in for a penny, in for a pound.
Curious: They claim they have a money-back guarantee - have you tried to get your money back? If they refuse to refund you still have hope, simply dispute the credit card charge. A credit card company will charge back a vendor on much less evidence of wrong-doing than you've presented here. There's nothing like a charge-back from VISA or MC to get a seller's attention - just call customer service for your card, they'll send you a form, and its a done deal.
