You bought it. There's no refunds from the PPV provider or UFC. They don't care if it "wasn't worth the money". They only care about the PPV buyrate.
Again, the Dana White thing goes back to him being a massive douchebag.
A lot of fans want to see fighters given financial penalties for not fighting, like they did in pride.
I still think Silva's next ppv is not going to net a lot of money for the UFC. Not just because of the recession.
