Robux bought from the Xbox website are tied to Xbox. They are not delivered as a code.
If the purchase shows Completed in Microsoft order history, the purchase went through on Microsoft/Xbox’s side. In that case, the missing Robux is typically a Roblox-side crediting or sync issue.
Recommended checks:
- Open Microsoft account Order history and confirm the Robux order shows Completed.
- If it is completed, fully close and reopen the Roblox app on Xbox and check the balance again.
- If the Robux still do not appear after that, contact Roblox Support so they can investigate the account credit.
- If a refund was already auto-rejected, Microsoft’s refund policy for digital goods is strict, and digital items are generally not refundable unless the offer or applicable law says otherwise.
Also important: Robux purchased through the Xbox Store are for Xbox and not provided as a redeemable code.
