These folks don't know what customer service is. When I called in to make a flight chance I was put on hold (someon answered asked how they could help, listened than please hold) for over 45 minutes before I hung up. I emailed them while on hold which is what they ask you to do and 3 hours later with no one calling me to discuss they closed my request saying it had been resolved. Be careful! They're playing a shell game.
