If you go to the Travel Tools on the SWA website, there is a link for View Ticketless Travel Funds. Click that and enter your confirmation number and it will show you the amount of funds you have available. There is also a link to request a refund, so you could try that and see if they will give you a refund. They might not, but it can't hurt. Also, when you book your next flight, when you get to the payment part, there is a place to enter you ticketless travel funds and you just enter the cancelled confirmation number and it will apply the funds to your new flight.
