Fisk and Joao Falcao e Cunha3, in their research presented the results of a qualitative study of a Portuguese bank regarding customer use of internet integrated in a multi-channel offering that includes high street branches, telephone banking and automatic teller machines.

Nelson Oly Ndubisi and chan Kok Wah5, in their research the results show that five key dimensions, namely: competence, communication, conflict handling, trust and relationship quality, discriminate between customers in terms of perceived relationship quality and customers satisfaction. Moreover bank-customer relationship quality discriminates between satisfied customers and those who are not. This study adds value by unveiling the key antecedents of relationship quality and customer relationship management.
