GM Gave me 264 loot, but should have been 277

Our guild did H Gunship on Thursday night, this past week, our raid id is 49618036. We wiped, but were able to successfully end the fight with dialogue and everything. The chest, however was unlootable and our GM put a ticket. This morning I checked my ingame mail and without looking at the item level (because I thought it was going to be 277) I took the two items that were going to be given to me. One being Ikfarus's Sack of Wonder and Boots of Unnatural Growth. The chest I took from the mail box, but didnt equip and the boots stayed in the mail the GM sent me. I also took the badges. I am putting this post on this forum b/c I don't want to wait another week for this to settle.

TLDR: GM gave me 264 loot, which should have been 277. Our H Gunship chest wasnt lootable and created this fiasco. Check my raid ID, we did H Gunship 25, please fix this.
