请教各位大神，
最近有一票海运，已发货和已收货 数量对不上 ， 已发货数量57，已收货只有24. 开case请求调查 需要提供购买证明（发票）。
我们发票基本是3个月一起开把数量全开在一起，所以发票数量是400 而不是 57。品名是中文名加英文名（标题关键词缩写），不是ASIN的完整标题。
第一次我上传的是比创建计划日期早20天的发票，文件是jpg格式（直接用手机拍照的）。
然后亚马逊回复：
Thank you for writing back to us,

Please note that the document was reviewed and not accepted.

To help facilitate faster research, please provide an Original invoice, previous invoice provided by this case not passed the system check : 

The invoice must be the original invoice, show the purchase of the products from a supplier or manufacturer, and include: 
* The date of that purchase
* The titles of the missing units
* The quantity purchased
* Full name and address of invoice issuer
* Full name and address of purchaser

If you are the manufacturer, please send a copy of the packing slip, which must include:
* The date of delivery
* The titles of the missing units
* The quantity shipped 

Once we receive this information we will be able to continue researching this matter. 

Thank you for selling with Amazon,
 
第二次 我上传了 UPS的签收单， 收到了同上面一样的回复。后来咨询了下朋友，说是只要发票或者采购单的数量和已发货数量对应上就可以。于是我又再次上传了发票（JPG格式）+采购单（中英文）
然后收到了亚马逊的最后一封回复
Please be informed that since you are unable to provide us with the Invoice document, which is essential as per our protocol:

A) We will be unable to proceed without the document 
B) We will be unable to keep the case open once more awaiting your document

We will therefore be required to close this case.

We request you to create cases for shipments while keeping your documents in your possession already, and attaching them to the case at the time of case creation, in order to avoid this situation in the future.

麻烦大神们帮忙看下 为什么发票总是通不过？ 我又找做申诉的服务商咨询，服务商也看了我的发票说没有问题。请各位大神赐教。
PS：很害怕一直提交不过 惹怒亚马逊店铺被审核啥的
