What should I do if China Mobile is maliciously opened with a monthly rent of 888 yuan?

It's simple. First of all, you should make sure that it is not what you asked for, because they will have corresponding supporting documents when they handle it, such as recording, SMS, website operation, copy of ID card and signature.

They can't prove that you asked for the opening and directly asked for the refund of the corresponding fees and the cancellation of unnecessary packages (just dial 10086 to handle it). If they can prove your presence (including phone calls, text messages, etc. ), even if you don't want to or are cheated by them, then I'm sorry, you have to pay the money that month, but they can "help you" cancel the subscription from next month, but! ! ! But you must see this "but" clearly. If you sign the relevant free mobile phone or other products with them, it will not be so easy for you to unsubscribe.
