Unfortunately, returning in-game currency after it has been spent is not possible.
Our game works in a real-time online environment, where every purchase and action can influence the gameplay of other players. Refunding spent currency, especially for completed actions or items already received, would break game balance and give an unfair advantage.
To keep the game fair and enjoyable for everyone, all transactions with in-game currency are considered final. Please be careful when making purchases to avoid accidental spending.
