Hello there,
We sell research books on Amazon under the name <business_name>. We have two platforms:
1) <business_name> (Canada)
2) <business_name> (United States)
However, in our Seller Central account, we see another marketplace named Amazon.com (United States) which we did not create. In this account, it looks like some Gift Cards are being sold for a while by someone else (which we never listed and never sell). And to our utter surprise, there are thousands of customer messages claiming the refund for Gift Cards they appear to purchase. We are totally confused and scared at this. How can we get messages from "customers" for the product which we never listed and never sell? And scaringly, they are claiming for refund *from us* which we never listed and never sell/sold. Could you please help us understand the situation?
Kind regards,
