I've alerted amazon to this via email, chat, and even phone.
They barely even take note, or act like they care.
I've written reviews disclosing this, Amazon denies publishing them, or they are removed after.
I cannot belive they care, not when they could open packaging and verify customer claims.
I even sent back an item, with the bribe/review scam which was inside the box, taped to the outside of the box.
Amazon does not care. It would reduce profit to care, and their actions show they do not care.
Always watch what people do, not what they say. Amazon's actions are clear here.
