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.
It sucks, but good luck
