Voice of the customer data is invalid - period - end of story.
The Voice of the Customer data is invalid because Amazon tolerates buyers abusing the self-service return platform and selecting the wrong return reason codes (and entering gibberish notes in the text box when forced to enter characters) to circumvent paying for original shipping plus the return postage label. It also provides a backstop to return used items to circumvent restocking fees.
Amazon facilitates this buyer fraud by creating an environment where the seller is financially damaged for receiving negative feedback or other negative performance metric strikes for assessing a proper return reason code and deducting these aforementioned expenses from the refund.
Please let me know if you disagree and you’re an Amazon seller.
