Hi @Seller_gAhPNiLrkfTcr

Can you please help with this order (206-2649502-6841157).

The customer placed an order with us and we dispatched the order to the address that customer provided in the order and tracking show proof of photo and gps but customer state that "it was never received" and left us a negative feedback. Can you please review and help to remove the feedback for us.

Thank you,

Sai

Order 204-9073402-4368304. Buyer cancelled order almost immediately after purchasing the item. I refund within 10 minutes and they left a negative feedback with the comment "Na". The removal system and appeal denied my requests near immediately. Is there anything that can be done to help me here? See timeline below. I am not sure how else I could have handled it?
