Were you offered the option of waiting for the next AA flight in which F was available?
People should just sue AA in small claims court when they pull this. It would be helpful to have a record of what the lowest coach fare at the time of booking was, but as others point out there's other ways to make a reasonable determination when AA tries to defraud you like this.
