About a month ago, I received a message from a buyer who claims the package was never delivered but USPS tracking indicates otherwise. I started a forum discussion on that topic here: https://sellercentral.amazon.com/seller-forums/discussions/t/c16413d0-ab10-42cb-9b32-02c3ad8176e4?postId=441c1aec-c9a1-4949-b339-2a38844be3a0

He sent me 9 messages requesting that I refund him $123.52 for his missing package. After I explained to him how to file an A-Z claim, I marked the last 6 messages "No reply needed" and reported him as trying to deceive or defraud me. Then he finally opened an A-Z case which was withdrawn by Amazon because he did not reply to their request for additional information.

A few days after the case was closed, I received a message that was supposedly from "Amazon Customer Service" but it I think it was from the buyer because it came through the message system with the buyer's name in the heading. I also marked this message "no Response Needed" and I reported the buyer. I'm copying and pasting the message below:

Is this a "fake" message from amazon? Am I doing everything possible to ensure that this scammer does not succeed? How can I prevent a possible negative feedback or chargeback if he keeps this scam going?
