FBM return auto-authorized and the customer hasn’t got the package yet.

Hello there,

I just had a customer ask for a return for a item that hasn’t arrived yet, the reason given was “no longer needed”. Not sure what the best move is here, I don’t want to refund them as the product is in transit and in perfectly good condition.

Talked to someone via chat at Amazon and they couldn’t have been less helpful.

Please advise, and thanks in advance!
