What should I do if the balance of Harry Potter's treasure cabinet is missing?

1. First, check whether the balance has been deducted by mistake. System failure or network problems in the game will cause the balance to be deducted by mistake.

2. Secondly, contact the game customer service, explain the situation and provide evidence and materials to seek the help of the game customer service.

3. Finally, pay attention to protect account information, don't disclose account information to others at will, and change passwords regularly.
