How to unbind VIP or remove VIP sharing?

Regarding VIP account binding in-game, please note the following policies:
1. Binding is Permanent:
Once accounts are successfully bound in the VIP Center (https://vips.99.com/web20/COindex.aspx), you cannot manually unlink all bound accounts directly.

2. Automatic Unbinding via Main Account Upgrade:
The only way to release all bound accounts is under this specific condition:
a. If your Main Account’s Credit VIP level is below VIP7, you can upgrade it by making a recharge.
b. After successfully upgrading your Main Account’s Credit VIP level, all previously bound VIP accounts will automatically unbind.
c. You may then choose to bind new accounts or re-bind the original ones.

Important Notes:
a. Automatic unbinding only triggers when upgrading your Main Account’s VIP level.
b. There is no manual "Unbind" or "Remove Sharing" option in the VIP Center interface.
c. This process only applies if your Main Account is below VIP7 before recharging.
