Hey there!

Nice to meet you! I'm Darhyl, a fellow gamer. I'm sorry you are experiencing this. I am here to help.

He can still try to claim it, if it didn't work try for him to use a different device and redeem the 25-character codes by signing his account on redeem.microsoft.com

However, if it still doesn't work, you can request a refund by signing the account where the Fortnite dollar pack was purchased on the refund webform and follow the instructions here on this link:

After submitting the request, your refund will be accommodated within 72 hours.

Thank you for your time. I hope you have a great day!
