For any business, the customer is very important and if there is no customer you can't do any business and you can't get any profit. A company will do the business to get some profit only. No business is done for service. If your business has to flourish you have to attract customers. At the same time, you should not lose your existing customers. A customer loss will be more dangerous than not getting a new customer. If a customer is lost, definitely he will talk bad about the company and product. That negative talk will make the newcomers hesitate to come. So every business person should give maximum importance to the customers and no stone should be left unmoved to retain them. That is the reason all companies will see that they will have a good customer service department and try to satisfy them with their immediate response and service. I have seen many companies losing their customer base mainly due to their bad customer relations. Customer is the important factor in our business but he is never a dstrubance.
