Never pay extra for premium seating on this airline

Just got ****med by FlySAfair.. I am a tall person so I select the option with more leg room whenever available. I checked in online and pre-booked the emergency aisle seating for an additional R60 each way.. when I arrive, my seat is a standard seat and the emergency aisle seats were booked out to other passengers. Will never fly this airline again. If you don’t want to lose your money, never pre select your tickets on this airline.. you’re paying for nothing.
