You came here and posted about the problem you are having with a purchased download you made for your Kindle. Members have provided suggestions how how to get your book back. You do not want to follow that advice. Right now you just seem to want to vent, which is fine but keep in mind whatever problem you are having it rare. If you are willing to work with Amazon it will be cleared up. The majority of us have had good or great customer service for our Kindles.
Think positively.
