Query: My package was open BLAME ON SELLER

Product is really good, my concern is not about it, it is about delivery method used by Amazon, I heard my door knocked, when I open my door the delivery van was just leaving, so nobody else could have touched my box besides delivery crew, well ...my box was not completly sealed, i could get my product from the box without using a box cutter. Seller is responsible of making sure product reaches the costumer safe and untouched.
