This is a user to user support forum, so we are unable to process refunds for you.
However you can Request a refund for apps or content that you bought from Apple
If the above steps do not work, I would recommend contacting apple support and request help with billing
Note: If you or a family member bought an item by accident
If you or a family member bought an item by mistake, set up Screen Time to prevent unintentional purchases in the future. You can require a password for purchases, prevent some types of purchases, or disable purchasing completely. Set up Screen Time.
Keep in mind that refunds may take 3-7 business days (or longer, sometimes even 30 days) to appear back on your account. This is because Apple's billing department needs to process the refund and communicate with your bank or credit card provider. The wait time is dependent on how efficiently your bank/credit card provider can process the refund. This is typical for all purchases on and offline. Refunds are processed back to your original purchase method.
