I ordered a book from AbeBooks via Thiftbooks. This was an out of print music book and was to be a Christmas gift. A book arrived and was placed under the tree. On Christmas, it was discovered that Thiftbooks has mailed a children's novel rather than the book ordered. That day, emails were sent to both companies explaining the error and asking for the correct book to be sent. A week later, I still have not gotten anywhere with either company, although Thiftbooks says they do still have the book I paid AbeBooks for. Almost daily I hear from a different person at AbeBooks who seems to not understand that the wrong book was delivered. It is impossible to actually speak to a person to solve the issue. I work in sales and if I treated my customers this way, then I would be out of business. This is dreadful customer service.
