Happened to me with a phone. Lego can check the completeness of packages by weighting grams, Amazon can't check the weight of a package with a phone ? Only could solve the problem with the help of the police. Then they would not cancel the attached carrier contract (which does not make sense without the subsidized phone) because they said Amazon's systems can create contracts but not cancel them. Again only the police helped. In the past I've got sent sometimes used electronics sold as new - recently I got 3 times used electronics as new in a row. Isnt that fraud?
