Gamepass Subcription date error is messing with a promo

I subscribed on 10/31

have a confirmation email dated 10/31

iI played my first gamepass game on 10/31

Im posting on 10/31

But billing is marking it as 11/1

Im doing the gamepass subscription as part of a promo that needs to be done during Oct

The billing date is going to disqualify me from the promo and cost me 10$ worth of swag

Phones and chat are down til tomorrow

How do I get credit in the promo and receive my swag

Xbox Quests

Except this isnt a xbox rewards promo

It is a gamepass promo under the guise of a xbox live promo in the games with gold section being conducted by helloworld

so not a xbox rewards promo

 

I used a gamepass in dev mode...

I bought Xbox one X yesterday.

There is a promo gamepass.

First, I make an account "*** Die E-Mail-Adresse wurde aus Datenschutzgründen entfernt. ***". and run retail-mode.

Beacause I heard the there is Dev-mode in Xbox, I run to test Dev-mode.

In there, I used my promo game-passl.

I thought that my gamepass available in same account.

(but... it's wrong..)

Then, When I returned to retail-mode, game-pass is no longer valid.

and also, I can't buy a new gamepass in korea.

(it occurs error. It shows, "Change Microsoff store area", PUR-ConversionBlokedCurrencyCountryMismatch blahblah...)

In dev-mode, language was Korean, Area was American. (I didn't check it properly.)

I want to use gamepass in Korea.

If not possible, I want to buy a new gamepass in korea account.

My account is "*** Die E-Mail-Adresse wurde aus Datenschutzgründen entfernt. ***".

please Help me.
