Query: Not a full version

I think I was cheated. This e-book is not a full version. I brought e version because it was handy to read. The most important thing is to get a useful book. Not a summary which is least expensive. I rather to pay more to get a full version instead of a short e version. This is the first ebook I brought and I was so disappointed. I don't know I should consider a ebook as what I want or not.
