Refunded amount is not full.

Hello nads04,

Thanks for posting here on the Apple Support Communities! This is a place where other Apple users can submit questions or respond to others to help lend a hand. You were refunded less than expected. Right?

When a refund is approved, it is refunded to the original payment method. So, if you used store credit for part of your order, check that as well. Have a look at Check the status of a refund for apps or content that you bought from Apple which advises how long each refund method can take.

If you have further questions, you can also contact Apple Support. You can reach out from Get Support or using the direct phone number for your region from Contact Apple for support and service.

Take care.
