this story makes absolutely no sense...no gate agent is going to try to convince you it said seat 12 the whole time...you can always just refuse to get off your seat and i doubt they would forcefully remove you from a seat you paid for...that's grounds for suing and the airlines knows that basic stuff. Also, when the couple first got their exit row seat, they had to check a box that said they are able and willing to perform the duties of those sitting in the exit row...did they read that in english and mark the box? The airline would most likely have bumped them from the flight rather than play these shenanigans. the OP is prob just looking to stir up some trouble...
