IEThe best customer service! I had a great experience with the platform. It is easy and friendly to use. I also had excellent customer support with GUY; he was patient and helped me in each step of the process. ISBN Direct has a robust system, a well-structured platform, and a masterwork of assisting clients.

GBI was a little doubtful of the ISBN number… I was a little doubtful of this company because the price was very low for an ISBN. But I used the number in my book, and now my book can be purchased on Amazon and other places. Thank you very much for your service.
