If your refund is approved, the funds are applied to the same payment method that you used to buy the item. Here's how long it takes for a refund to appear on your account or statement:

• Store credit – It might take up to 48 hours to see the refund in your Apple ID balance.

• Mobile phone billing – It might take up to 60 days for the statement to show the refund. Processing time might be affected by your carrier. You can contact your carrier for an update.

• All other payment methods – It might take up to 30 days for the statement to show the refund. If you don't see the refund after 30 days, contact your financial institution.
