Delivered a damaged bag

We had a long day getting back home from Fort Lauderdale to Las Vegas yesterday. Multiple flights changed, delayed, rerouted, and more. We made it home. Our checked bags didn’t. No worries. We figured that would be the case. We stopped at the luggage office in LAS and gave them the descriptions and chose to have the luggage delivered to us. The luggage arrived in Las Vegas this morning, and was delivered late afternoon. One of the bags is severely damaged. Handle broken, 2 bottom wheels smashed, and the hard shell broken in multiple spots. SW is telling us we have to go back to the airport to file a claim, and if not done within 24 hours of delivery, it will be denied. The airport is an hour each way for us, and is chaos right now. We also work full time jobs, and can’t get there in time. I am reaching out to other departments and numbers, but is there anything else we can do? I filed a complain online, and included pictures, but there is nowhere to file a damage claim. Any help is appreciated.
