搬瓦工能不能暂停服务（保留 credit 留到以后再用）

没有吧，他家都是年付的， 30 天内退款。话说他家的够便宜，只要不是特别高配置的，没必要去折腾？

Cancellations and Refunds

Customer may cancel the service at any time from their control panel. We do not impose any restrictions on cancellations. A full refund will be provided upon request if service is cancelled within the first 30 days of activation. We can only refund one service per customer account. Refunds are not provided for services that were suspended due to Terms of Service violation (s ).

To request a refund, please submit a ticket to our Billing department and it will be processed within 2 business days.

大部分普通商家都是这样的。比如你买了一年，但是用了半年后删掉了机器，最后会把一半的钱退到账户里，以后还可以继续用。

比如我的 BuyVM 就是：
Available Credit Balance: You have a credit balance of $70.53 USD and this will be automatically applied to any new invoices

忘了说了：
搬瓦工我没用过，所以不能保证他家也是这样。
你可以先开 ticket 问问，就说现在删除机器后能否把剩余的钱存进 account credit 里。
