I ordered a book that never shipped even though they had long since charged my credit card. After several emails they agreed to send the book again. The second book never arrived either. They said they would credit my account, but they never did. They promised to try crediting the account again, but still nothing. Finally they promised to mail me a check. That was more than 2 weeks ago, and the check has still not arrived. They have also stopped responding to my emails.
