I haven't received my in-app purchase
Sometimes a situation can arise when a player spends money on a purchase, but resources aren't added to their account. This is extremely rare, but it is possible. In this case, please, wait a little while (it can take from a few minutes to a day).
If the resources still haven't been added after 24 hours, please submit a ticket to the technical support team directly from the game (Settings → Support → I haven't received my in-app purchase).
