At the beginning of the month, the SMS service was obviously cancelled when the card was replenished. Why did I find that China Construction Bank still deducted my 3 yuan SMS service fee from the prepaid account, but I didn't notice it? 1. Cancel the SMS service in the current month, which will take effect next month, but still deduct the money for the current month.

2. After the construction, if you want to cancel any monthly fee deduction service, you can go through the cancellation procedures near the end of the month. Anyway, it has been deducted that month, and it will take effect in a few days to next month.
