Please stay away from Chegg! By far the most unprofessional, displeasing, unhelpful, and runaround company I have ever come across. Representatives are ill-informed which caused me to return a book I was told I would be refunded for. The book was returned and they notified me the reimbursement cannot happen because I bought the book under "purchase". So now here I am book-less and money less. So much for helping college students. DO NOT USE CHEGG, IT SCAMS AND DECEIVES THROUGH ILL-INFORMED REPRESENTATIVES
