The document discusses customer services delivered through social media channels versus traditional channels like hotlines. It presents research on how customer service quality, satisfaction, and outcomes like loyalty differ across these channels. An empirical analysis was conducted comparing customers' service experiences through a hotline versus social media. The results found that quality of interaction and reducing customer effort were more important drivers of satisfaction in social media, while quality of solutions mattered more for hotlines. Customer satisfaction also had a stronger impact on loyalty when created through social media services. The research provides implications for optimizing customer service strategies across channels.
