I placed an order for a book around the time my program was starting, I entered correct payment and shipping information for it, Knetbooks confirmed my order and charged my card (the correct amount was taken out of my account), and Knetbooks cancelled my order without warning two days later claiming something was "inconsistent" with my payment information. I reached out several times for clarification on the issue and to offer more information if necessary, and never got a response. Now I am stranded without the book and have missed 2 weeks of school content because of this issue. Thanks for nothing!
