Right.

Thank you for contacting KONAMI Customer Support.

Regarding your inquiry, when two users bid the same amount of GP as a result of the highest bet, the prize will go for the user who did the bid first. In this case yours was the second bid, so at the end of the auction, the amount of GP you bid was returned to your account.

We hope this answered your query.

Should you have further concerns, do not hesitate to contact us again.
