This is a value-added service. You can check online in the business hall to see how many months of charging records there are, and then call the value-added service consultation and complaint number 10 109696 to ask him to help you understand how the service is customized. If there is a recording, let him play it for you. Pay attention to the charging time in the recording. If the customized program is illegal, or he can't make a recording, then you should ask him to refund all the fees (even if he has booked it for several months) and ask him to help you cancel it. Pay attention to the attitude must be firm and tough.
I hope it helps you. Please accept it if you are satisfied.
