If they actually cared I'm sure there would be a way to report these kind of issues. I got physical mail about submitting review for a product that I bought from Amazon (sold by company X, shipped by Amazon) in exchange for Amazon Gift card. The mail did contain name of the product. I tried to report it and

* there was no obvious way to do it. Closest thing was by reporting issue on product.

* there was no way to show the customer service agent a picture of the mail. Chat did not support sending pictures & they were unable to open imgur link.

* agent recommended me to leave a report it by leaving review to the seller page. I did that and next day review was deleted.
