In this ever-changing market‚ it is not only the encoders talk‚ the decoders matter as an equal. One of the main objectives to maintain consumer relations is to build brand loyalty. What an organization claims or promises will be evaluated by its consumers and other stakeholders‚ meanwhile‚ the perceptions of authenticity

Communication is the lifeblood of an organization‚ an institution and even the individuals themselves. It is the bedrock of pleasant ground and good relationship between the communicator and receiver. Kottler (1977:125) defines communication as ‘a process consisting of a sender transmitting a message through media to a receiver’. For the purpose of the purposes of the presentation‚ lecturer according to Pradhan (1977) is an oral presentation of information and idea by a person to a large group of
