我在Kohls下了一单，第二天单子被砍了。过了一个月，发现cashback balance有一笔
负100多块，日子正好是下单的日期，但找不到正100多块的记录。
NM，咱shopper的账号啥时候成了商家的ATM了？
跟shopper联系，他们要求提供如下信息：
The information you have included is incomplete. To properly investigate any
purchases, we do need the complete email receipt that includes:
1. Purchaser's full name
2. Merchandise price
3. Date of purchase
4. Method of payment used
5. Shipping confirmation
问题是这交易根本就被取消了。应该怎么办？
