Unicom's broadband Internet access is very slow. How should I complain to them?

1, call 100 10 customer service hotline to transfer the manual service.

2. Explain to the customer service staff that the object of the complaint is broadband service, because the broadband network bandwidth in the broadband service is not up to the agreed value, express the desire to solve the problem as soon as possible, and leave contact information.

3. The customer service staff accepts the complaint and waits for the staff to contact and solve the problem.
