Call and complain. You can probably get flight or atleast baggage fees reversed, and they definetly will replace the item.
Or, just go through the proper channels being understanding and polite first and see how that goes. You catch more flies with honey than you do with vinegar. Those people are quite used to people calling and bitching at them. You'd be surprised what a bit of genuine politeness and understanding can get you sometimes when you're dealing with people who are accustomed to seeing people at their worst.

From my understanding airlines have never repaired this shit or replace it.
You can try to file a claim but i wouldn't get my hopes up.
TO be honest with my bag you could drive over it and nothing would happen to my board still. That's why i got that bag.
It's the same with golf clubs, if i just throw duct tape onto my golf bag and expect my driver to make it the whole way i'm fucking dreaming.
