How to get a refund by credit note to my bank account

Hello Ouazzani,

Thank you for posting in Apple Support communities. We understand that you are wanting to know why your refund has not been sent to your bank. We would love to help you with this. 

This resource tells you how long it takes for your refund to be sent back to the payment method used for the original purchase: Check the status of a refund for apps or content that you bought from Apple

Thank you for allowing us to support you.

Have an awesome and productive day!
