Thank you for all the people replying. When my citadel was 12the level I 'd demanded my missing crowns in the game. I 'd sent a ticket by using ticket missing section in requests section. This ticket was denied by email. Because as You mentioned above duty was 13th level citadel. Then when I had 13th level citadel I made a snapshat with my mobile and replied this email with this snapshat attachment. Today I recieved an e mail that is approving my crowns. By the way it can take alot of time to get replied. Be patient if you are in the same situation.
Thank you for your helping .
