I sent my Samsung s21 5G for a trade in for an s23 to samsung using their shipping label via Fedex. The package was weighed in as 1Ibs at the time of shipping. The trade in triage period for samsung is 2 weeks, however after 21 days samsung rejected the trade in and charged me 433 dollars. I reached out to their customer service who said they had recieved an empty box. They asked me to file a police report and fedex complaint for a refund. I did that, and when I went back for my refund, they refused stating that they had video of opening an empty box. They do confirm the weight at the time of shipping, which was 1lbs. They then again encouraged me to reach to fedex. Fedex stated that since shipping was paid for by samsung, they are the ones that need to open the claim. However samsung has refused to talk to fedex. There are thousands of google inquiries for customers who have been told by samsung that their package was empty. Samsung needs to understand that they are responsible for the shipment and it's insurance with fedex. Either Fedex stole it, or a Samsung employee. Look it up before you do business with them. There are thousands of posts on reddit and elsewhere about people who are told their packages were empty. As of right now, Samsung has refused to issue a refund.
