The coins were taken away, but the pack was not given

Hello! For the first time I encountered such a problem, in the process of buying a pack worth 275 thousand game coins, after payment, the message "about store overload" popped up in the game menu, but the coins were debited from the account and that was it. It's been more than a day, and no coins or pack have been provided. Can you tell me how it is possible to solve this situation?
