Thanks for the helpful information. I would file in NYC, where the ticket was purchased and I live. I've made one last request to customer service, who as before told me that I could check my credit card statement in three weeks and see what the refund department in all their wisdom has decided. This is the most infuriating system--those who decide about refunds are completely insulated from customers, and customer service agents take no responsibility for their decisions.
