I purchase a new galaxy S21+5G from Samsung and was told if I return my old Samsung Note 8 phone I would be given a $300 credit towards the new phone. I received my new phone and set it up and reset my old phone as instructed by Samsung and returned it in the same box that they sent me my new phone to Samsung with their shipping label thru Fedex. A week later I get an e-mail stating that the box they received was empty. I called them and told them it was not possible and told them exactly what the phone was wrapped in in the box. They said it was the wrapping I told them but NO phone. After looking into the matter further with the Fedex person at the store where I shipped it from she explained that the box showed a weight of .80 lbs and said if the box was empty as they claim the weight on the box would be much less than .80lbs. Now I am disputing the chargeback of $300. with my credit card company and Samsung has told my credit card company that I cancelled my order that's why the chargeback. Samsung is lying on 2 counts, one the box was empty and two I cancelled my order. Someone in their warehouse took my phone from the box because it was in perfect condition. Stay away from Samsung offers as they are dishonest.
