Missing 2 purchases of blitz packs, fix store?

I am playing on pc and I bought the 8.99 and the 19.99 blitz pack purchases, both have been charged to my Microsoft account yet neither purchases have registered in game and I’m convinced that it will be like this for any purchases I make, for some reason my store is broken yet I still get charged and the packs never register, I would appreciate a halo support member to credit my game the packs… my gamer tag is toxic psycho420, please and thanks for any help, and any clue how I can fix the store for future purchases??
