GTA+ is a digital Xbox subscription, so it follows Microsoft’s digital purchase and refund rules.
To fix a purchase made on the wrong account, the only option is to request a refund on the account where GTA+ was actually bought, then repurchase it on the correct Xbox account.
Follow these steps:
- Sign in with the Microsoft/Xbox account that was used to buy GTA+.
- Go to the Xbox support page to Request a refund for digital games: https://support.xbox.com/help/subscriptions-billing/buy-games-apps/refund-orders
- Select the GTA+ purchase and choose Request a refund.
- Provide the reason (purchased on the wrong account) and select Next.
- Review the details and select Submit.
Refund requests can take up to 72 hours to process. Status and updates are shown on the Refund status tab. If online refund is not available in the region, contact Sales support using the guidance in the references.
After the refund is approved and processed back to the original payment method, GTA+ can be purchased again on the correct Xbox account.
