Customer Loyalty can be difficult to define given the different views that are presented within the literature. Zithaml, Berry and Parasuraman (1996) determine that loyalty includes a customer’s intention to stay with an organisation and that loyalty includes four elements: repurchase intentions, recommending the service provider to other customers, less complaints and tolerance of price increases. Oliver, (1999) provides a different definition and describes loyalty as a customer’s overall attachment to a product, service, brand or organisation.
A better appreciation of the factors that influence the loyalty of customers, particularly their attitudes and changing needs can help companies to develop strategies to prevent customer defection
(Coyles & Gokey, 2002). Customer loyalty is important as it can have a powerful impact on a firm’s performance and it is considered to be a source of competitive advantage (Lam, et al., 2004).
There is a strong level of agreement that customer loyalty and satisfaction are linked; however, there is an absence of consensus as to what constitutes customer satisfaction (Caruana, 2002); in addition, despite the fact that many loyal customers are satisfied, this does not always translate into customer loyalty (Kuo & Ye, 1999, Jones & Sasser, 1995) and studies have shown that satisfied customers may express a desire to switch to a competitor but it may prove to be difficult due to a lack of suitable alternatives (Pantouvalkis & Lymperopoulos, 2008, citing Mittal & Lassar, 1998). In contrast however, Reicheld & Sasser, (1990), indicate that high customer satisfaction should provide increased loyalty, which makes it less likely that a customer will decide to switch to a competitor.
In addition to customer satisfaction, it has been suggested by numerous Researchers that there are other key antecedents to customer loyalty including perceived value, service quality, corporate
