Buyer put in a cancellation request and when we were processing the order we canceled the order as that was what was requested directly by the buyer. How were they even allowed to leave feedback on an order they requested be canceled. I hope someone from Amazon will see this and review this as this must have been a mistake by the buyer and or system. The buyer left feedback saying they never received the order that they asked to be canceled? And I can't even contact the buyer to ask it be removed because they canceled the order.

We have a buyer that signed for a delivery but has claimed that they did not receive the item. Signing for a delivery is proof that the item has been received. We submitted this, but the bots that run the A-Z Claims still denied us and allowed the buyer to steal the item. Can I have a Mod looks at this and see if there is a way to reverse this?
