Hello JunYoung,
Sorry to hear you're having issues with your bill. I understand we have previously have been able to discuss those matters via PM here in the forums. However, you should note that the forums are community-driven and are no longer intended as a venue for customer services. While there may be some moderators still willing to provide assistance via PM, you will likely need to contact customer service so they can look into your account. In addition, they can also be contacted via Live Chat, Facebook, or Twitter. Those methods can be accessed via the contact page posted above.
Hope this helps 😀
Cheers
