it is better to teach customer service skills with conversations in the polite and systematic way.

By answering yours studied questions and by testing the different attitudes.

To be flexible and understanding, patient and clear in your explanation. 

Customer service is in-built skill.
If you are doing JUST to each and every customer, you are automatically satisfying the customers.

A company's reputation isn't solely based on the products it manufactures. How customers are treated plays a part in their overall opinion of the company and what they say about it to their friends and family. Having good customer service can set your business apart from competitors and keep customers coming back.

1. Talk to employees about basic customer-service skills in group settings, if possible.

2. Offer examples of poor customer service. Most people have experienced poor customer service at least once in their lives. Ask employees to share such experiences and how they made them feel. Encourage employees to discuss what could have been done differently so the customer would have had a positive experience instead of a negative one.

3. Encourage role playing in group sessions. Allow participants to try out the skills you are teaching by role playing with one another.

4. Watch employees practice the skills they learned in role playing in actual customer interactions. Give them feedback after the customer has left about what they did well and what they can do better.

5. Remind employees about what is important. Employees can become complacent about customer service over time.

For developing customer service skill first of all the agnet should be taught how to give speech. Many agents are very good but are very fast speakers, the person against him is unable to understand what he is speaking. The right way to speak with an customer will be.....like taking a pause after2-3 sentences and take note that customer is understanding you. Another good skill could be while supporting customer make him/her understand by an good example(always give examples which relates to clients work/job/family).

Training, we had so many training sessions of how to deal with customer and help them listen first and then how to react to different tones in the custoemrs voice to understand what emotion the customer might be going through before helping them out.  Another key is taking feedback from your customer service employees, if lots of customers are complaining or employees are complaining about a product or their job, there has to be something wrong there which needs to be dealt with.
