The good news....
Through the attention of freespiritguru I have now received a one-time exception to their policy of a $39.95 credit toward future travel.
I was a $9 Fare Club member for only 45 minutes through a misunderstanding on my part that it was required even to see the Club fares. This is incorrect. The fact is that the fares are visible beforehand if you pay close attention to their website. The lesson learned here is NOT to join the $9 Fare Club until you are ready to book and take advantage of one of their promotional fares.
I also learned that they have an 800 # at which you can talk to a human. This is on their website under HELP item #5.
I don't know much about Spirit Airlines, but I am v encouraged that they have an active presence on FT....
