After spending $120+ (I can't recall the exact amount) because it was required for my class I was not able to get into my book since day one. After having my teacher look into it and after she was unable to help me I was cast away on my own to figure the problem out (apparently the link within canvas would connect me properly to Cengage, surprise! it didn't) after sitting on the phone for almost two hours and letting the lady on the phone take control of my laptop she simply said she couldn't figure it out either, she told me she would forward my problem to the Cengage developers and they would send me an email with a resolution to my problem in no more than three days, that was a month and a half ago and Im sure you can guess I never received an email or email conformation to keep me updated with the issue. Still to this day I have not been able to access my online book or any of the learning material that are required, if I didn't buy this from the college bookstore I would have gotten a refund but I simply cannot do that. This has been an absolutely terrible experience and I can promise myself one thing, if I know that a teacher is using this platform or intends to use this platform for teaching class materials I simply will not take that class as because it is that bad. I have stressed over this issue, I have gotten angry with this issue, I have shed real tears of frustration because of this issue and I have yet to find a solution no matter what I do. In my 20 years of living on this earth I have never wasted my money or my time like I have wasted it on Cengage.
