The study was guided by a research schema which was the basis for the formulation of five conceptual hypotheses. Five relationship marketing tools – communication, commitment, trust, promise fulfillment, and social bonding – where all explored to determine their predictive power on a bank customer retention. A structured questionnaire was designed on a five-point like scale. Data collected were tested using Pearson Product Moment Correlation Coefficient (PPMCC). Statistical support was found for all the dimension of relationship marketing as predictors of bank customer retention. However, commitment, trust, and promise fulfillment are the strongest or most potent predictors of bank customer retention, while communication and social bonding are weak predictors of bank customer retention of lecturers within university campuses. Hence, this study posits the Commitment-Trust-Promise Fulfilment Model of Relationship Marketing, thereby challenging Commitment-Trust Theory of Relationship Marketing. Key recommendations, with their concomitant managerial implications, include: first, banks operating within university campuses should make adequate budgetary provision for the purpose of executing a sound relationship marketing programme for its bank customers who are university lecturers; second, training and retraining on a constant basis in the area of relationship marketing (with strong focus on commitment, trust, and promise fulfillment) can be conducted for the marketing staff of banks operating within the university campuses.application/pdfAC Collections.
