Amazon will not even look at our appeal.

Amazon have asked us to submit information, which we did.

Then they said we didn't reply so they close the appeal.

Then we contacted seller support which advised to reply to the case from the case log.

Then we have replied to the case showing a proof that we submitted the reply on time.

Amzon did not ask us to re-submit our reply with attachments but replied to us -
