How can a book writer can help for managing a brand?

Managing customer reviews is a difficult task for my company. As our organization was established one year ago, the customer service still requires improvement and upgradation. I am looking forward to having assistance from professional book writing services that help us guide how to promptly respond to customers' queries. They could train our customer service representatives in communication skills, conflict resolution, and product knowledge. The Customer service training will enable them to handle customer queries and complaints effectively. Moreover, they will gain knowledge of how to keep a social media page and promptly reply to customers through emails. I have searched for a few potential book-writing companies. I would be glad if any colleague recommended to me the best services they have availed.
