I could have taken more screenshots to back myself up but I really didn't expect an F fare even booked in 'A' to be a saver, lesson learnt for the future I guess. I am hoping their email which clearly states the fare to be FLEX is my ace card.
Anyway, the return leg is at the end of august so I shall contact EK then assuming they only credit saver miles. I shall try even if it takes 7 months.
