The service of Zhuhai Tietong is very poor. Where can I complain?

I didn't register Baidu until I saw someone say Zhuhai Tietong.

How about Zhuhai Tietong? Who will regret it!

Tietong's maintenance personnel don't know how to access the website. They will only tap the keyboard with one finger, enter the account password and establish a network connection for you. If it's English, they won't!

I can't help it, but I don't need Tietong in the future.
