I am limited by You Tube to 15 minutes per video, thus all the lectures.

With each lecture, find similar information covered by the Customer Service book and read those pages as well. When you register and pay for
the certification you will get the book.
Customer Service Lecture 1 Why service matters, customer service, customer loyalty, lost customers (15 minutes)
