I ordered books for the Spring semester knowing I would also need the same books for the summer semester. When I received an email at the end of the semester stating, "If you want to extend your rental period, do nothing, and we will charge you the extension fee after 06-01-2012." Unfortunately, I thought this was telling me I could easily extend my rental fee for the next semester. The thought never crossed my mind that this email was strictly to extend the due date, especially for the amount they were charging. Why would I ever want to extend the due date? I always send my books back on time so to extend a due date was never something I even considered. So, when I was charged the 22.12 for one text and the 23.66 for the other text I thought I was set for the Summer semester. I was wrong, this morning my account was charged right at 300 for both books with the option to send the books back within 4 days from the date on the email and then I would get a refund. Yes, it was my mistake to assume the statement on the email meant something entirely different than the way I read it and I should have gone directly to the sight and not put my trust in an email from a reputable site. Anyway, I thought surely there would be no problem with this misunderstanding so I contacted customer service. They said they could do nothing and I would have to send the books back for a refund and re-order the books if I still needed them. I have been a customer for over 2 years and both of my children will be in college for the next 4 to 6 years. I have told countless people about Cheggs and have never had a problem until I actually needed them to help me. I asked them to simply allow me to extend my rental of the books which is exactly what I thought I was doing to begin with and then refund me the difference. I am shocked that they could not or would not do this type of service for a customer that has been using them for over 2 years. The school my children are attending now offer the option to rent books. Since I was a loyal customer with Cheggs, I never used this option. Starting this Fall, I will no longer use Cheggs but try the rental option with the school.
