I want to return the package business and expenses of Bailing K-Song 20 yuan.

Mobile users can try to cancel the service in the following ways:

1. Mobile users can log in to the mobile phone business hall client of China Mobile APP or 10086APP, select the business to be cancelled through the path of My-Done Business-Unsubscribe, and unsubscribe according to the prompt information on the page. The above path is subject to the actual information displayed on the processing page.

2. Send SMS 0000 to 10086 to inquire about the related services that have been opened. If you need to cancel, you can reply to the corresponding serial number within 2 hours before the service.

For some businesses, self-service cancellation through the above method is not supported at present. You can call 10086 to contact the manual customer service to unsubscribe, depending on the actual situation.
