Customer service is a very broad term; what are the most important features of customer service?

I think customer service is about building a relationship and just like in personal relationships, things are not always done perfect and on time, in customer relationships things cannot always be done in this way. So, it is important to build a strong relationship so that it continues even when requests are not fullfilled on time or by the requested standards. To build this relationship, understanding, patience and communication abilities are essential.

It's the quality of product/service which affect customer service most. Apart from that there are many other factor which advesrly affect Customer Service such as Face Value of the product/service, Seperation Anxiety (Words of Mouth), Price fairness, product expertise, understanding Customer expectations & needs,and  technical support/advice.

The most important features are:1) to UNDERSTAND the needs of the customer ( it happens that the customer doesn't know himself/herself what he/she really needs).
So it's important not only to listen, but to see through what is the need.2) to be respectful and kind ( to be tolerant is also a MUST)

TO deal with customer very efficiently and listen the customer very carefully what is he/she demanding

For me is to have a100% knowledge of the product they are dealing, because if they have this matter will go of having a100% percent of giving good customer service as well, and the others are to have a strong and good personality and must have knowledge how to handle a customers complaint as well...
