Paid United in Stormwind Tavern Pass but not arrived

Hello, I have paid United in Stormwind Battle Pass recently, transaction is in pending state. App was hanged while “authentication”, after 30 seconds i closed it. . Used my Apple Heartstone client, content still not arrived. I guess Blizzard wont try to get the money, if Revolut charge back the money (10 days) , can I buy the pack?
