I submitted a trade in for the S21 Ultra which gave me $600 off the phone. I received my phone and sent my trade in. I was informed that the box in which my trade in was sent was empty and they want to charge me the $600. I honest to God sent my phone in. It looks like someone along the way stole the phone out of it. I have a supervisor at Samsung who is going to call me back. Has this ever happened to anyone else? Now I’m out $600 and an iPhone 12 Pro Max? Doesn’t Samsung or UPS have insurance that covers this kind of thing?
