Hello melih3413,
Thank you for using the Apple Support Communities. We understand the importance of keeping track of your refund status, and we have a resource that should help out.
If your refund request was approved, you can use this link to Check the status of a refund for apps or content that you bought from Apple.
- Go to reportaproblem.apple.com and sign in with your Apple ID.
- Choose Check Status of Claims. If you don't see Check Status of Claims, you don't have any pending refund requests.
- To see the status, tap or click Pending."
Regarding the timeframe for a refund, it depends on the payment method:
"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."
Best wishes.
