They usually always reverse the refusal to approval. Pictures are really useless as there's nothing saying a person didn't remove the item after taking pictures, video a little better if you have yourself filmed the whole process with the box continuously in the video.
I personally think Samsung was so used to FedEx workers stealing items they mostly reversed the rejected email.
My biggest nightmare had is this....I've been thru the FedEx and Samsung BS before. The package was not delivered and way past due with no tracking showing anything. I contacted Samsung with the I have pictures of everything and they didn't want the pictures so they said to contact FedEx and file a claim. I contacted FedEx and they said to contact the party that paid for shipping, Samsung in this case and have them file the claim, only the shipper that paid for shipping can file a claim, and you guessed it, Samsung sent me back to FedEx. I was on the phone a lot with FedEx and they issued tickets finally. Fortunately for me a couple weeks later the package all of a sudden was delivered, just got a the package delivered email.
Like I said, for the most part Samsung reverses the rejected emails. If it never gets delivered, it's a fun time promised
