I keep being asked to verify my payment through my Amazon account every time I purchase a book on kindle. It is very frustrating and hasnt been resolved despite two calls to you. Im being told its for my own security but its ridiculous to do this complicated runaround to purchase books. I can understand one purchase but multiple ebook buying is nonsense. My order for a book called 56 days is saying incomplete payment and directs me to your site. Another complicated series of actions brings me straight back to the start.
