A higher amount than I tried to charge was withdrawn.

When you charge points using simple payment services such as Toss, Naver Pay (Npay), or Kakao Pay, there may be cases where a higher amount than you intended to charge is withdrawn. This is not a payment error, but a situation where the points were charged using the prepaid top-up method of the simple payment service.

• If the balance within the service is insufficient at the time of payment, a preset minimum amount (e.g., 10,000 won, 50,000 won) is automatically topped up first, and then the payment is made.
• The remaining balance after payment does not disappear, but is kept as a balance within the simple payment service. 

Please check the remaining balance after the top-up within each service as described below.

Toss Pay

• After accessing Toss, go to [All accounts] > [Points • Pay Money] and check whether the remaining balance after charging POSTYPE points is stored as Toss Pay Money.
• If the balance is insufficient, 50,000 won will be automatically topped up and then used for payment, and any remaining balance after the top-up will be stored as Toss Pay Money.
• From Toss Home > top right [Payment] > [Payment method] > [Settings] next to Toss Pay Money > [Transfer], you can select the account and amount to transfer and withdraw the remaining balance.
• For more details, please contact the Toss Customer Center directly. 

Naver Pay (Npay)

• On Naver, go to [Npay] > [Points] > [Money] and check whether the remaining balance after charging POSTYPE points is stored as Npay Money.
• If you used the Npay Money "Scheduled Top-up" feature, when your Npay Money balance is insufficient, the designated amount will automatically be topped up from the linked account and then used for payment.
• If a charged payment is canceled, the amount is refunded as Npay Money, and the refunded Npay Money can be withdrawn to your bank account without fees.
• For more details, please contact the Npay Customer Center directly.

Kakao Pay

• In the KakaoTalk app, go to the bottom [···] (More) > [pay] > click [Money balance] > [Money history] and check whether the remaining balance after charging POSTYPE points is stored as Pay Money.
• According to Kakao Pay policy, if your Pay Money balance is insufficient and a bank account that allows top-up is registered, Kakao Pay will automatically top up Pay Money in units of 10,000 won and use it for the payment.
• For more details, please contact the Kakao Pay Customer Center directly.
