I ordered a the textbook Security in Computing 5th Edition. The process was quick and easy, however the textbook I received in the download was the teacher's manual. I contacted the company and they refused to provide a refund even after I provided screenshots of the introduction saying "This is the teacher's manual" and the teaching outlines in the chapters. I double checked the page I ordered the book from and no where does it mention that it is for the teacher, the cover exactly matches the textbook (word for word, number for number).
I will not be using this company anymore.
