是用paypal 嗎？
是的話就是要在paypal裡面改。
（小弟之前也是無故被扣款）
在[my account]裡面的[profile]點進去。
有個[Recurring Payments]點進去。
裡面就是每月定時扣款的項目。
去取消掉就好了。

您用的那個連結，
是用來刪除bdg免費帳號的。

如果你是用你的 PayPal Account 給錢的話,
Login 進你的 PayPal 直接取消 subscription

不用寫信給他們啦
==========================================================
If you would like to cancel this subscription, log in to your PayPal account and go to the "History" subtab of the "My Account" tab. Choose "Subscriptions" from the pull-down "Show" menu and press the "Submit" button. Choose this subscription, and click on its "Details" link. You will be taken to a Transaction Details page from which you may cancel your subscription. Cancelling your subscription will immediately stop all future scheduled payments for this subscription.
