Help! Refound on banned account

Hello, I'm going to expose my sad story hoping some one can help me.

I had get in touch with Xbox support on Twitter and they have told me they cant help, so I am lost.

I bought a game for my Xbox One S directly on the xbox page on browser, they accepted my pay and charged me for 1599 pesos inmediatly, after that I tried to log into my console but was unsuccesful, so I was searching for help here and there with no luck,
on the xbox support page I am unable to log in, for getting a refound or something.

After several attempts I realised the account form where I bought the game was banned from Xbox Live, I really couldn't remember until the enforcement showed up (By signing in on xbox.com).

Now I want to get a refound so I can get the game on other profile, but I can't since the support page (msft.it/6017p1ZkL)
nor the refound request page (msft.it/6012p1ZKs ) allow me to log in.

Please if some one could help me in terms of getting the refound I will be so grateful.

:)
