Organizations should ensure that any complaints from customers about customer support have been dealt with effectively. Automated customer service Customer service may be provided in person (e.g. sales / service representative), or by automated means, such as kiosks, websites, and apps. An advantage of automation is that it can provide service 24 hours a day, which can, at least, complement face-to-face customer service. There is also economic benefit to the firm. Through the evolution of technology, automated services become less expensive over time. This helps provide services to more customers for a fraction of the cost of employees' wages. Automation can facilitate customer service or replace it entirely. A popular type of automated customer service is done through artificial intelligence (AI).

Another form of automated customer service is touch-tone phone, which usually involves IVR (Interactive Voice Response) a main menu and the use of a keypad as options (e.g. "Press 1 for English, Press 2 for Spanish"). In the Internet era, a challenge is, to maintain and/or enhance the personal experience while making use of the efficiencies of online commerce.

But this lack of visual and tactile presence makes it even more crucial to create a sense of personal, human-to-human connection in the online arena." Examples of customer service by artificial means are automated online assistants that can be seen as avatars on websites, which enterprises can use to reduce operating and training costs. These are driven by chatbots, and a major underlying technology to such systems is natural language processing. Adversely, automation has created a need for information that can sometimes harm privacy. Metrics The two main ways of gathering feedback are customer surveys and Net Promoter Score measurement, used for calculating the
