This is Sonny from Amazon, here to help with your negative feedback received and impact to order defect rate. Thank you for details on your situation, let’s look at next steps to resolution.
An important benefit of using Amazon’s Buy Shipping service is if you ship on time with tracking via Buy Shipping, and the buyer leaves seller feedback solely related to delayed or undelivered packages, you can request to have the feedback reviewed. A great resource with details on the use of Buy Shipping services can be found here.
Was the request submitted specifically in your feedback manager? It is imperative the request for strike through is submitted through the feedback manager for review by the correct Amazon team. The strike through request may still be under investigation to meet the required criteria. Please review this important help page for striking of feedback, and here is why:
You can request for feedback removal only via Feedback Manager . Contacting our Support teams through ‘Contact Us’, or any other methods to request for feedback removal, other than the Feedback Manager, may lead to account deactivation. Removal requests must be made within 90 days of the feedback submission. The system prevents feedback removal after 90 days.
I hope these points can help you with your resolution. The forums community is here to support you. Keep us posted with any updates!
