When will I get my money back after refund request?

Read this support article for information about how long it takes to receive a refund, and how to check the status of 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 - Apple Support

After you request a refund you'll receive a status update by email within 48 hours. If your refund is approved, the funds are applied to the same payment method that you used to buy the item. How long it takes for a refund to appear on your account or statement depends upon the payment method used:

● Store credit—It might take up to 48 hours to see the refund in your Apple Account 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 [e.g., credit or debit cards]—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."

Since the article specifically says "statement", which for me is the thing that arrives monthly in my mailbox, I wonder if you check your daily card transactions online if you might see it earlier?
