The rise of social media in the 21st century further transformed customer service, creating a public forum for interactions between consumers and brands. Customers began to expect immediate responses to their inquiries and complaints, leading companies to adopt more proactive strategies. Social media platforms became both a channel for customer service and a space for brand reputation management. Businesses that effectively engaged with customers on these platforms were able to build stronger relationships and foster loyalty. As a result, customer service evolved from a purely transactional interaction to a more holistic experience that incorporated brand values and customer engagement.
