我利用支付宝在一美国空间商处购买了一空间和域名,现在我想退掉空间,域名保留,以下是他们发给我的邮件,请帮忙翻译下,
Thank you for contacting Online Support.Unfortunately we are not able to provide partial refunds to Alipay orders at this time.In order to refund this order we will need you to respond to this message with the last 4 digits of an alternative payment method,agreement to pay $10.87,and acknowledge that you have read and agree to our universal terms of service.Once you have provided us with this information we will be able to refund the full Alipay order.Please let us know if we may be of further assistance.
第二段：
Thank you for your response.As stated before,the purpose of the fee is to keep your domain active.When you make a purchase in Alipay partial refunds cannot be done.For this reason,we would need to refund the entire receipt.The only way for this to be done would be if you paid for the domain or if you canceled your domain.Please note that you will not want to cancel your domain is you still have use for it.If you wish to keep your domain,state that you accept the charge of $10.87 USD and the last 4 digits of the payment method you would like to use.If your preference is to use Alipay,please respond stating this and we will place this charge into your account.We appreciate your patience in this matter.
谢谢下面的回答，但我要的不是用软件翻译出来的，那个我也会，关键的一点“the last 4 digits of an alternative payment method”这个是什么？因为我是用支付宝付款的，但我要退一部分钱，而支付宝是不接受部分退款的，所以他们可能让我提供另一种退款方式，而这个“the last 4 digits of an alternative payment method”可能就是，但我不不知道是什么方式，有人知道这个吗？

感谢你联系在线支持,很遗憾此时我们不能提供部分退款给支付宝订单,为了退回这次订单的款项我们需要你提供最后4位数的另一种支付方式回复给我们,同意支付10.87美金,并承认您已经阅读并同意我们的普遍服务条款,一旦你提供这些信息给我们我们便能退回全部支付宝订单.请让我们知道是否能提供更进一步的援助.
“谢谢您的答复.如前所述,该收费的目的是保持您的域名有效.当您通过支付宝购物是不能部分退款的.基于这个原因,我们需要退还全部订单的话,唯一的途径就是购买域名,或者取消购买你的域名.请注意,你不会想取消您的域名是你仍然使用它.如果您想保留您的域名,阐明你接受支付10.87美元的费用并想使用最后4位数字的付款方式.如果你的偏好是使用支付宝,请回复说明这一点,我们将会把这笔费用存入您的帐户.我们非常感谢您对此事的耐心.”
