Customer service is the fulfilling right expectations of 
customer when he buys the product. When customer buys any 
product he may not be aware about the use of product or may 
he gets some issues with the product. So resolving queries 
or educating about product this could be the goal of a 
customer service. It is as simple as the example of our 
own. When we buy any product we get queries, and if there 
is no one to resolve our queries, we either throw the 
product away or get frustrated. 
A good customer service is a good way to grow the business.

we should satisfy the customer by providing him whole 
informatoin about services
