Customer left bad feedback for my company because he was unhappy with the amount of credit given him (partial) by Amazon customer service. My request for Feedback was denied. How do I appeal this incorrect decision?
You can wait a few days and open a new case. This time, use the Seller Support Chat line. Many sellers are find this method effective, when all other attempts have failed.
The reasoning you can use is that the entire thing is a product review, or a fulfillment issue,
