Hi mayson guerrero,
I'm sorry to hear about the trouble with the gift card. I can understand how frustrating it must be to purchase a card and then find that part of the code is missing.
Since you have proof of purchase and Xbox Support has already advised that the issue needs to be reviewed by Microsoft, I would recommend contacting Microsoft Support directly and providing any evidence you have available, such as your receipt, photos of the gift card and details about the missing digits. Their support team is best placed to review the card's status and determine whether any further assistance or replacement options are available.
To contact Microsoft Support:
- Go to the Microsoft Support contact page and sign in with your Microsoft account.
- Type "Live Support" and select Get help.
- Scroll down and select Contact support.
- Under Products and services, choose Other Products.
- Under Category, select Billing and Account Profile questions, then select Confirm.
- Choose Chat with a support agent in your web browser.
Please note that this is a user-to-user support forum. Moderators and contributors do not have access to billing, redemption or account systems and cannot arrange callbacks or issue replacement gift cards on Microsoft's behalf.
I hope this helps point you toward the right support channel for further assistance.
Best regards
