So Ale damaged a splitboard similar to that a few years ago. He went to the shop and the asked them what they could do. The repair guy smiled and said he had just the thing to fix it up. Went into the back, came back with a beer, handed it to Ale and said "Sorry man you're board is done".
Pretty much the same here. Ouch. I would contact the manufacturer. Most do understand what this means and have some empathy for their customers. They may just hook you up with a deal on a new deck. Which is about the best you can hope for in this situation.
