Sales and Marketing
We locally manage our service offerings in an effort to serve the needs of each customer, and have sales representatives with local market knowledge relevant to the service territories in which we operate. We operate approximately 20 retail stores and two wholesale call centers, located mainly in our local service territories. We also have automated many of our customer service functions, including Internet e-commerce systems, so that our customers can receive answers to many frequently asked questions regarding their communications services without speaking to a customer service representative.
