Wait, did you do same day standby or same day confirmed? Those aren't the same thing. It sounds like you should have done SDC (if there were F seats available) and never been on the list at all, so yes, you should definitely file a report about this.

I ended up forcing them to refund the charge and got a $100 voucher. Numerically that's fine and all, but the supervisor was so offensive I had to threaten to take my business to another airline.
