How do I get my money back after iTunes say I got my refund but i don’t get it

From the third link below. "Allow up to 48 hours to receive an update. The time it takes for the money to appear on your account or statement depends on the payment method."

But, if you think you still have a problem with a subscription or a purchase, see Subscriptions and Purchases https://support.apple.com/en-euro/billing. If you think you are owed a refund, then use the request a refund link. It will take you to Request a refund for apps or content that you bought from Apple https://support.apple.com/en-euro/HT204084

See How long refunds from the App Store or other Apple services take https://support.apple.com/en-us/HT210904
