Service mishaps highlight disconnect with users

A middle school teacher contacts parents of his students in Beijing. My telephone operating company's official website commits to a round-the-clock customer service hotline, providing services such as inquiry, consulting, failure reporting, handling of complaints and suggestions, business transactions and recharge service. Even in such a monopolized market, post-sales service has, to some extent, affected the business revenue of the fixed-line telephone operator. Another reason for the company's business revenue shrinking was the decrease in fixed-line telephone subscribers nationwide due to the strong challenge from mobile services. I really hope the current decrease in fixed-line users does not become an excuse for my telephone operator not to provide a quality post-sales service to its customers.
