I purchased an ebook and they said I had to get the Bookshelf app. I would not have purchased it had I known this. But OK, I didn't click on the little question mark which stated this, so buyer beware and "No Refunds." Anyway, the email instructions said to download the app which I did, and to create an account, put in your redemption code the book will be available. However, the app only offers the ability to sign in and does not offer the ability to sign up. So I have been waiting for way too long for the chat on the Bookshelf site, and it finally gave me a message that they are busy and to send an email instead. Too bad I can't read the book I just paid $71.00 for. Thank's Wiley. I'm sure the hackers can get at these, but you are preventing your paying customers (or former customers in my case) from obtaining the book they paid for. Good Job! Whey I tried to go to Wiley's support page, it says to log in, but when I do, it says I am already logged in. Again, it gives no other options so you are in a loop.
