I asked for a refund, but at the time when the money was returned to me, my card was blocked and the money did not come

Here's what Apple has about the flow of refunds:

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.

For apps and media you can also sign into https://reportaproblem.apple.com to check if the status of your item is "Refunded".

From: 'Check the status of a refund for apps or content that you bought from Apple' --> https://support.apple.com/HT210904

If you need to contact Apple about this, click on this link --> https://support.apple.com/choose-country-region/ and choose a path that gets assistance from Apple staff.

They don't say this anywhere but I believe if they cannot refund the original payment process they will instead add a store credit to your Apple ID balance. Have you checked that?
