What does Beijing, Zhong You and Wan Wei do? My mobile phone was deducted more than 20 yuan by it, and I don't know how to deduct it.

I have encountered such a situation, and the deduction of more than 20 is less. At first, I was detained for almost 300, 40-50 a day. My solution is to restore the mobile phone to the factory state (mine is only a mobile phone), and then install 360 mobile phone security guards. This method is probably useful for ordinary mobile phones.

Deduction means sending text messages and calling customer service without your knowledge. They say there is nothing they can do. That's disgusting.
