Abstract: Courier services are essential to the smooth running of modern commerce. The advent of e-commerce has revolutionised the retail industry. In tandem, courier services have evolved and become more sophisticated. The courier industry is seeing a rise in quality-conscious consumers who know what they should demand from their service providers. This article reports on a study that examined the efficiency and timeliness with which professional couriers made their deliveries. This research is among the first to apply concepts from knowledge management and logistics management to the courier service sector.

 The researcher has gathered the necessary data for this study by administering a questionnaire. The goal of data analysis is to summarise and organise the data acquired in a way that provides answers to the research questions. This is accomplished via the use of a variety of interrelated statistical methods.

To investigate the causes of complaints, questionnaires were distributed. A total of twenty-four questions were designed to elicit the desired information from the respondents. Eighty participants served as the primary data source. The study's data was examined with the help of the chi-square test and the simple percentage approach.
