How many DAYS does it take to receive a DIGITAL E-BOOK from Amazon?

I purchased an ebook last night(pdf) from Amazon. Here I am 24 hours later and the ebook is still not ready for download. My order info says “Open Order — Being Processed”. I used their click-to-call help service twice today to find out why I should have to wait ANY amount of time for a digital download. So far, no luck.

Bogus.
