I have had multiple issues with this company. I have even emailed them several times with no response. Today is the last straw! I have an assignment due and after logging on, the "read book" link keeps going back to the login page. Even the "need help" link, logs me out and says access denied. Please people save your money rent or buy a used book on Amazon. I will NEVER use this service again. And I will warn any fellow students who will listen!
