我的亞馬遜賬號突然不能銷售了，不知道是因為客戶投訴還是其他原因？

前兩天有個產(chǎn)品listing突然顯示“不可售”，Seller Performance Team發(fā)郵件讓我提供發(fā)票、收據(jù)等材料：
“Hello,
We are reviewing your selling account and we need to verify your documentation for the following items:?
XXXXXXXXX
Please email pq-review@amazon.com with the following supporting documents:
Copies of invoices, receipts, contracts or delivery orders from your supplier issued in the last 90 days. The quantity of items shown on the documentation should match your inventory...”
然后我就發(fā)了，但他們一直不回我，去催了一下，結(jié)果直接說我不能銷售了：
“Hello,
Based on the information you provided, you may not sell these items on Amazon.com. We removed your listings for the following items:
ASIN：XXXXXXX
Please do not relist these items. If we receive more complaints about your listings, we may not allow you to sell on Amazon.com.
To learn more about our policies, search for "Amazon Anti-Counterfeiting Policy" or “Intellectual Property Violations” in Seller Central Help.
Sincerely,”
不知道是怎么了，我在想是不是有客戶去投訴了？因為郵件里有提到“complaints”這個詞，而且之前有客戶給了2星差評，還有個客戶要求退款（商品價格挺高的）。。。
