Hi @Seller_TD8kClMwLYBMd,

I think I can help explain what might be happening with your chargeback response options. According to the help page (https://sellercentral.amazon.com/help/hub/reference/G202145040), there's a 7-day window to respond to chargebacks: "You must respond to any chargeback claim within seven calendar days of the email date."

If you're still within that 7-day window and can't find the "Represent your case" button, try checking both the "All" and "Action Required" tabs on the Chargeback Claims page. The help page mentions this button should appear under both tabs.

Can't find the button at all? You can also respond by simply replying to the chargeback notification email from Amazon. This is mentioned in the "Respond to a chargeback claim" section of the help page.

One important thing to note - the final decision process can take up to 90 days, and Amazon will only email you about the outcome if you're financially responsible for the chargeback. If you end up getting debited and believe it was a mistake, you can still reply to the chargeback email to request a review, though the help page does mention that the issuing bank's decision is usually final.

Best regards, Michael
