Amazon owns a ripoff company called Woot, hundreds of BBB complaints. The policy is to get order, have Amazon charge the credit card, and THEN send you a email informing the customer that there is no warranty and no returns on the defective junk they are going to ship you.
Amazon will tell you, they can not or will not help you. Woot could care less, they have 100's of complaints and are proud of the fact that they do not even look at them, let lone respond.
Amazon will "refund and charge back" if it is a out side vendor, when it involves a company they own their policy is to send a automated email telling you to go away
