Dealing with complaints
Customer may not be always right, but it is often
worth letting him feel that way.
Complaints are, within certain limits, a natural
business phenomena. Therefore don’t feel guilty
while communicating with customers.
Complaints need not always be concerned with
the quality of goods, but may be linked to their
use and application.
Don’t try to reason with any angry customer.
Don’t create differences by giving loose words
Always let the customer feel that his complaints
is being taken seriously. Keep him informed and
avoid delays.
