Query: Amazon really Dropped the Ball on this one!!!!!!

I ordered this book, asked for overnight shipping because of a deadline (the book was needed for a school report) and only learned the day it was supposed to arrive (afte receiving a confirmation that the book was in stock and would be there on time) that I would not receive it until 5 days later! I called Amazon to cancel and they also cancelled my 90 free shipping trial and refused to reinstate it. It was probably the worst online buying experience I have ever had.
