Query: Learn Microsoft Visio

This has been the worst Amazon experience I've had to date. You sent me the wrong book. I called and told you, so you sent me a replacement. You sent me the wrong book AGAIN! I called and told you. I asked that you physically confirm that it is the correct book before sending it next time. The Customer Service person would not do so.Now I have 2 wrong books and no Learn Microsoft Visio 2002. I am expected to go on the computer and print return labels, then go to the post office and ship the stuff back. Seems to me that I am being seriously inconvenienced for your mistake.
