Mojang Eerie office failure to gain item

I've already tried contacting Mojang about this 3 times before the event even ended and keep on getting my ticket closed and the same automated message. The event just ended, but might as well Try to do this.

 

 

 

Essentially, I completed the requirements for all 3 rewards and got 2 rewards after refreshing the game. Weirdly, the mojang cap wasn't given to me but only the cape and shirt were given to my account I tried refreshing and resetting the game, but nothing worked, so now I am here. Thank you to everyone.
