I ordered a 3-months rental and the books I received were horribly damaged! I contacted customer service and the bookrenter promising to expedite the shipping of a replacement. But I never received anything and contacted them again asking what was the problem. I was told that my books are no longer in stock. I told them I will keep the damaged books since I need them for my work. But they said that I already ordered a replacement and their system will not let them change it, so I will have to return the damaged book back within 30 days or I will get a punishment. I was like „Is this a joke? If it is then it is not a funny one!” Well that's fine by me, I will never order from them again!
