我刚才申请然后提示的是：
Your payment method requires you to make a one-time, prepayment. Once this prepayment is credited to your account, you'll also receive your free trial credits and your free trial will become active. This prepayment is refundable if you choose to close your Cloud billing account
是不是得手动去关闭那个账单现在然后才能把押金退回

我看翻译过来的意思是：
您的支付方式要求您一次性支付xxx元作为预付款。一旦这笔预付款存入您的账户，您还将获得免费试用额度，并且您的免费试用服务将立即生效。如果您选择关闭云服务账单账户，这笔预付款是可以退还的。

关闭云服务账单账户才能退回 还是和之前那种验证了就退回呢
