Xbox series X not showing up in order history- why?

like the title says im having issues tracking my series x order. I can do so via the email but not thru my purchase history.. I did call support and got an answer that was basically I cant see it on my end etc.. it does make me nervous. he blamed the
website updating .. my brother however does have the xbox series x in his purchase history. In addition to that does Xbox just keep charging our cc until they ship? and has anyone seen the other authorization fall off? im not seeing that on my Amex - it looks
like double charges.. Xbox not very helpful tbh. Its more like a have faith.. No big deal I can do that I was expected to get mine by 12/23.. anyone help? why cant xbox set up support chat instead of a continuous loop on support numbers. is this one of those
things that it depends who you speak to at microsoft and you may get a better answer??
