Hello Littlecup,
Welcome to Apple Support Communities!
If we understand your post correctly, you've gifted your husband some audiobooks but he is unable to redeem them. We're here to help!
Have you tried resending the audiobooks? If not, let's go ahead and follow the steps below:
If the recipient can't find the email with the redeem button, you can resend the gift.
- Open the Settings app.
- Tap your name.
- Tap Media & Purchases, then tap View Account.
- Sign in with your Apple ID.
- Tap Gifts.
- Tap the gift that you want to resend.
- Make sure that the recipient's email is spelled correctly. If you need to edit the recipient's email address, tap their email address, then tap it again and enter the correct address.
- Tap Resend Gift. If you don't see Resend Gift, it has already been redeemed."
Gift apps, music, movies, and more from Apple
Is your husband able to download or update apps? If their account has been disabled, they should check out this article: If you see a message that says 'Your account has been disabled in the App Store and iTunes'
Thank you for using Apple Support Communities.
Take care!
