Bharti Airtel's managing director, Gopal Vittal, has called on the company's 19,000 employees across India to cancel business meetings on Tuesday and spend the entire day with customers to address service challenges they face. This is part of a national brand-building drive to position Airtel as a customer-obsessed telco, seeking direct market feedback on its 2G, 4G, and 5G mobile operations and home broadband services.
