Theoretical background: Consumers today are presented with a myriad of opportunities through which the purchase process can be realized (Yrjölä et al., 2018, p. 1133). The customer journey can be defined as a buyer's behaviour in a multi (omni) environment with the goal of finalizing purchase transactions and acquiring positive (seamless, holistic) customer experiences. Researchers look at a service buying process as the customer value-adding journey (Saghiri et al., 2017; Wilding, 2003) and its prime objective is to deliver a positive customer experience at each of stage of the buying process. According to media richness theory (MRT), voice-based communication is ranked higher than text-based communication along the media richness continuum (Daft & Lengel, 1984), however, some additional findings have been also revealed. Taking into account the traditional continuum of media richness, phone communications is perceived as rich in information; only face to face contact is seen as richer (Suh, 1999). As stated in Rhee (2010), customer-initiated communications via phone channel is preferred when the consumer faces an extended problem-solving (high perceived risk/low familiarity) situation. Whereas, in the case of routine problem-solving, the situation online channel is preferred. However, some relevant research on marketing channel richness has been proposed by Kwak (2012) as well as Lipowski and Bondos (2018). According
