Why was thirty yuan deducted from my postal savings card for no reason?

You may have noticed that thirty yuan was deducted from your postal savings card for no reason. This may be due to the customized SMS reminder service. The SMS reminder service will notify you of changes in your account balance in real time. It is usually provided in the form of express mail. The annual fee is 30 yuan and the monthly fee is 3 yuan. This is a common service at many banks, including Postal Savings Bank.

After you make a deposit, if the SMS service is set up, the bank will automatically send account change information to your reserved mobile phone number to ensure account security. In the case of netizen "Xi", his mother's bankbook was deducted probably because of this green card SMS service. The green card SMS service is designed to inform account transactions in real time and improve account security protection.

However, it is worth noting that this service is usually based on the principle of customer voluntariness and requires users to explicitly agree and provide a mobile phone number. If your mother did not express her consent when opening the account, you may need to further confirm whether the bank obtained her consent during the process. If you can provide your contact number and deposit account number, we can help you understand the situation and solve the problem in more detail.
