organizations in Viet Nam beside factors in original ACSI/ECSI model as: image, expectation, perceived value, satisfaction, complaint….Moreover author also considers the direct relationship between perceived service quality and customer loyalty instead of through customer satisfaction as the original ACSI and ECSI Finding: This study finds out that beside factors in original ACSI-ECSI models, service customization and communication also have positive affection to customer loyalty Beside that a direct and significant relationship between Perceived Service Quality and Customer loyalty is also recognized Design: This research has based on ACSI/ECSI model and ECSI extended models to measure Perceived Service Quality, Customization, Communication and Customer loyalty 200 questionnaires will be issued to collect data Limitations and implication: this study has its limitations in terms its scope which focused only Telecommunication organizations in Viet Nam Beside that many factors that can affect customer loyalty such as: switching cost, economic cost, transaction cost, call center, in-different services, price perception and inertia… are not mentioned in this study For business owner or directors of organizations, this study can help how to create Customer loyalty in their organizations This study is also helpful for researchers to extend its scope to other business field and other geographic areas outside VietNam Keywords: Customer loyalty, Perceived Service Quality, Service Customization, Communication TIEU LUAN MOI download : skknchat@gmail.com Table of

INRODUCTION 1.1 Research background As many researchers have conducted, customer loyalty is one of the most important thing in business nowadays, and that it is more profitable to retain customers than to acquire new ones (John, Katherine & Libai, 2003; Liz LeeKelley, Gilbert & Mannicom, 2003), so how to retain customers is one of the key of success of organizations, and especially in telecommunication business in Viet Nam where the market almost nearly saturated (P.V, 2012) so customer loyalty is becoming competitive advantages for organizations to compete, develop and survive on this market On over the world many models are used to measure customer loyalty such as: Servqual, Servperf, ACSI, ECSI… Telecommunication market in VietNam is now ready for matured with biggest suppliers: Viettel, MobilePhone, Vinaphone that got more than 95% market share (P.V., 2012) and other smaller suppliers: S-Phone, VietNam Mobile, Beeline (now is called G-mobile) Telecommunication market is now becoming the game play of big Viettel, Mobifone and Vinaphone There are few differences in Vietnamese telecommunication market between now and 3-5 years ago In the past how to attract new customers is the most important thing to service providers, service providers are always try to attract new customers as much as possible, but at this time this strategy is not the most important one, and in long-term how to retain customers is much more important than attracting new customers So beside of attracting new customers, how to make customers retain to service providers are considered carefully and become the critical factors for service providers to survive and develop in this market, so research on customer loyalty and its antecedents such as perceived service quality and other factors can be a very importance for service providers (Santouridis & Trivellas, 2010, p.332) Few researchers have also researched for customer satisfaction and perceived service quality in VietNamese Telecommunication market and most of them based on TIEU LUAN MOI download : skknchat@gmail.com TIEU LUAN MOI download : skknchat@gmail.com Table: Factor Matrix 2nd Factor X Offers products
