What a mess up! (Pre Order Armor)

ok I didn’t play on the magical date of 11/7/15 but I did pre order my game and I didn’t get my armor. what happened was my brothers file ended up getting the armor although the game is registered to my file. so he has my armor and I still don’t have any of my pre ordered stuff. and I was wondering if pre order stuff goes to both files? frankly I’m out right pissed at the moment. you guys should know -Yoink!- well who preordered and who didn’t, after all it was through my XBL account which I ordered, my credit card, my email, ect. now if I can’t get my preordered stuff then can I get something else??
