How to cancel the monthly fee for Monternet business?

The best way is to go to the business hall and ask the salesperson to help you understand what the monthly fee is like. They will copy some SMS access numbers for you, and then you can go online to find out which information companies these are, and then call customer service to complain about these information companies, saying that they give you a monthly subscription without your consent, and then ask him to cancel you all. Finally, I will transfer this monthly fee to China Unicom in the future, so don't move.
