jetblue changes flights unilaterally and will not refund you. Internet

I am highly disappointed by the customer service personnel at Jetblue. Overall, this was not a hugely expensive ticket (approx $500 total), and they couldn't just offer a full 1-yr credit even. I have been a loyal customer and a Jetblue credit card holder. I will be canceling my credit card and going elsewhere with my business. In a tough economy, the only difference between the companies is good customer service. Overall, I am more offended by the way I was treated over the phone. The manager didn't even offer to provide a new credit that expires in one year, even though it was Jetblue that changed up the schedules of the flights. If Jetblue hadn't changed the schedule, everything would be fine. Instead, I'm stuck with a credit that expires in under a year and having to scramble to find a new airline and canceling my credit card. If Jetblue had provided us with a little respect and courtesy over the phone, my feathers wouldn't be ruffled. I am just trying to get to my brother's wedding. I booked these tickets way in advance. I don't know what I did wrong to deserve this. This case will be reviewed by a complaint specialist at the Better Business Bureau, and then forwarded to the business for their response.
