You can't remove a listing from the internet. It is there to stay for ever.
What you can do is connect with each entity that lists your business and update your listing to inactive.

It depends on what you want. If you just want copies of your book to sell yourself, lulu.com or CreateSpace would be good choices. With them, you can also have your book for sale on the internet.

If you want to see your book in book stores, and have a chance of making some money on it, you need to get in with a traditional publisher. In traditional publishing, the publisher takes on the costs of getting the book published and available for sale. You, the author, don't pay anything. You get professional editing and cover art at the publishers cost.

The most common reason for a book not getting published is because the book isn't good enough. If the publisher doesn't think it will sell, they aren't willing to put their money behind it. Learn the writing business, learn how to write a really GOOD book, and your chances are much better.
