I need to wait or its already refund?

After you request a refund you'll receive a status update by email within 48 hours. If your request is granted, the money is returned to the payment method you used. The time it takes for the money to appear on your account or statement depends on the payment method:

- Store credit (e.g., Apple ID balance): 48 hours

- Mobile phone billing (payment through your phone service carrier): Up to 60 days

- Other payment methods (e.g., credit/debit card): Up to 30 days for it to appear on a statement.
