ah nope, customers open INR claim and i have proof of delivery with signature image as pdf but there's no option to upload it to Amazon. I have tried to attach the pdf and email seller guarantee but it doesn't show up on the claim either.
You actually have to email it to them as an attachment to seller-guarantee@amazon.com. If they request it, you can just reply to their email with it.
i tried to email them with attachment via seller-guarantee@amazon.com but it seems their system blocked my email provider. 3 months before, whenever i emailed them , a case will be create in my seller account but now, there's no case or whatsoever. This is really weird.
