Singtel still holds the largest customer base in Singapore. Even though many providers now offer cheaper plans and more free gifts, Singtel remains the market leader. However, they often ignore customer requests or charge monthly fees for services that may create extra costs, such as hiring more customer service staffs to respond, or to reset devices and restore services etc.
StarHub is the one that is really struggling, as it is losing more customers. Because of this, they are changing and becoming more willing to listen to customers. Maybe one day Singtel will drop to second or third place, and then they might start learning how to listen.
