美国亚马逊有个prime到底有什么用？而且还自动划了我的帐收了费用，怎么退出Amazon Prim

你肯定是点击升级为Prime用户，费用好像是一年79刀。
具体的取消流程是：先把去账户里把Amazon Prime 资格取消（首先找到亚马逊首页有一个try Prime ，找到有一个manage Prime membership，点击END membership，然后在弹出的对话框里点击确实END，就顺利退订啦。），然后到Contact Us里给美亚客服发信息（点右下角那个chat）确认是否扣款会还给我，得到了对方的肯定回复。然后就是耐心等着了。给大家看一下我和亚马逊客服的对话记录，以供发生类似网友们参考。
为方便大家拷贝我把文字部分粘贴如下。
