The worst structure in Customer Service, which is designed to entangle customers once you have paid your money, and then you will wish you had never bothered with these people. This business will not last for long, given the horrible way business is being conducted, and cheating customers out of their hard earned money, by switching items when delivering. To the unsuspecting customer, they will make millions by way of this bait & switch technique. I wish there was negative points and ratings. Jeff Bezos is a great businessman, all should learn from him. Innovate - dont imitate what you cannot copy.
