Query: Very bad quality binding

The content of the book is great for the most part. I have some issues with a few of the questions, but overall a great applicable text.The quality of the book is another story. Upon opening the text, the pages started to separate from the binding. I foresee them falling out in the near future. I paid well over $100 for this book, I expect it to be well made. Not something I could concoct with a piece of wood and craft glue.
