Hi,
If the purchase was made with Apple ID balance, your account balance should update within 48hrs form the date the refund was approved on RAP.
If the purchase was made with a credit/debit card, you should receive the refund back onto the original card charged within a few business days; it may take up to thirty to post on your statement as a refund or credit adjustment.
- Request a refund for apps or content that you bought from Apple
- Check the status of a refund for apps or content that you bought from Apple
Hope this helps.
