You see, China Post deducted my SMS service fee in 30 yuan without permission! ?

Have you started the call reminder service for balance change? 3 yuan can be cancelled at the counter or online banking every month.

Find short message service and other items in online banking, and remove the check mark in the small box after the mobile phone number.

Since the postal service has already charged, it is considered as operating income, and it is unlikely to be refunded to you again. The computer has been recorded and it is not easy to change.
