Minecraft bug - Personnal account

Hi,

I don't have any gift code to switch to the windows 10 Minecraft from Java edition.

Event when i've tried to redeem a code, nothing came to my mailbox or my account since over 4days.

I've tried to launch the game, and every other steps on every support website ether yours or Windows one, nothing change.

 

Could you help me find a way to get this gift code ?

 

Thanks
