I didn't receive a refund for a random subscription

On March 4th, I was charged 79.99 for the Duolingo app. I wrote to the support team on the 4th of March to return the money, because the purchase was accidental. Today, the fifth of March, I received a message in the mail that the money was returned to my card. but no money. no money, no subscription to Duolingo. It turns out that the subscription was canceled, and the money was not returned. please return my money to me

proof that there is no refund and subscription
