Reach out to Amazon
Go to the new support case in seller central. Next, go to customer feedback problems, which can be found under orders in the account settings. You must then provide why you think that the feedback should be removed. Finally, put in the real facts and figures back your statement.
Reach out to the customer
This is a sensitive process and requires you to abide by the rules that Amazon states here. Giving refunds or exchanges to the customers so that they would remove their feedback is strictly prohibited. Sellers are only allowed to respond to their feedback and explain how sorry they are about this bad experience. They can then offer an apology and ensure them that this will not happen again. While responding to their feedback, they can politely ask customers to remove the negative feedback.
If you are confused and still unable to find a way through the removal of negative feedback, then feel free to reach to us. We will help you get your business reputation back on track.
