Sorry you were ripped off but I do think you have case to go to the authroities in your state for Fraud based off of this statement on their website
"The VCP5-DCV certification has a VMware course requirement, which must be met in order to obtain the certification. Our program fulfills the course requirement and includes the VCP5 exam onsite, so you walk away with certification in 5 days!"
Which is patently false and I am sure VMware Education would assist you in identifying who you need to contact of course this all depends on how much effort you want to put into this.
