Spirit Airlines ripped off my daughter who was trying to fly in for her Grandma's funeral! Internet

I had to fly my daughter in for her Grandma's funeral Monday 10/12/09. SPIRIT AIRLINES quoted her $364 round trip, and offered her a $100.00 promotional discount. She verified the $100 discount several times. They billed me the entire $364. They scammed a young lady while she's grieving for her Grandma. The $100 discount they assured her of was for signing up for some stupid promotion, we she actually did, but still no discount. How much lower can you go than scamming someone who is trying ti get to a loved ones funeral. I complained to them, and this is their lame response:

 "I have reviewed your situation thoroughly, and found our records to indicate that your reservation was in fact confirmed. Please note that in order to proceed a customer must verify that the terms and conditions of the purchase have been thoroughly reviewed and agreed upon with one of our Reservation Agents.

Spirit Airlines has made certain that by reviewing these terms of purchase, the potential passenger would be made aware of any extra fees that could be associated with their travel. We are a growing airline and we are doing our best to train our employees to provide superior customer service. We apologize if the service did not meet your expectations"
