剛剛得到官方的回信

===============================================
Looking at your account, I see that our payment processor found your purchase of Guild Wars 2 met certain criteria indicative of a fraudulent purchase attempt.

As a result, our payment processor preemptively refunded the purchase of the serial code and returned the funds to the cardholder. Also as a result, the serial code was disabled and the account was permanently closed.

The account will remain closed and is not eligible to be reopened for any reason under any circumstances.

There is no further assistance we can provide for this issue. Further replies may not receive a response.

可是我的銀行跟我說有扣款 也支付了
我是在官網上買的
不知道是哪個環節出問題
