I had purchased an e-book for a college course and I was charged $135.00 for the e-book. However, I do not have access to the e-book anymore because you only have access for the duration of the class apparently,which I found absurd. Additionally, we only had accessed for about 2 months, probably not even a full 2 months since the course was an 8-week class. I have never come across something like this when purchasing e-books. Is there anything that can be done about this situation? Is the legal?
