Query: Disappointed

I was disappointed with this item. This was a Christmas gift for my wife and wish it would have not been defective. I wanted to return it and get a new one but Amazon did not have this option. However Amazon told me I could return it for a refund.Reason for return: Loud humming noise and the wire whip and flat beater struck the bottom of bowl despite making all adjustments as per instructions manual. KitchenAid, What happened to you quality inspection?
