Terrible customer service. Save yourself time, money and frustration and NEVER buy here! Bought two books and they send me the wrong titles. I contacted chat first. They couldn't give me a straight solution "because another department is responsible for that". I asked them to email me back with a solution. Not possible! I tried several other ways to contact customer service, but they just completely IGNORE me. Frustrated and tired of wasting my time, I sent back the books, and paid for the return shipping costs myself. TOTALLY UNACCEPTABLE!!! I've lost money and time and still do not have the books I wanted. I will NEVER buy from these ARROGANT people again! I wish I read the many, MANY bad reviews here before (all followed with a standard reply, underlining their lazy, impersonal service), then I would have never bought anything from them. Save yourself time and trouble and avoid these people at all costs!
