Why did China Bank deduct 24 yuan SMS service fee and 3 yuan?

I think I charged a small account management fee. You can go to the bank and ask how much it costs. Bank card annual fee and small account management fee can be cancelled. Users need to go to the bank counter to cancel their accounts with their ID cards and bank cards. Only one account in each bank can enjoy free annual fee and small account management fee. Moreover, users must take the initiative to apply, and the bank will not take the initiative to cancel these two charges for you.
