It provides telephone service, digital TV, and high-speed internet to customers primarily located in Missouri and Illinois, but has branches in Arkansas, Oklahoma and Kansas as well. The company offers reliability and consistency, featuring both DSL and fiber-optic technology solutions ranging from speeds up to 100 Mbps. In terms of customer service, Cornerstone provides 24/7 technical support and customer service representatives who are available to answer questions or help with the installation process. Its plans are designed to meet the needs of every customer, ranging from basic copper-based services to more advanced optional features like call-forwarding, three-way calling, and voicemail.
