Does Zhengzhou Construction Bank charge 30 yuan SMS service fee for one year or one month?

36 yuan a year, I have deducted it.

Moreover, the SMS service is deducted for one year at a time, and it will not be refunded if it is cancelled.

I did it last year. I said the first month is free. Forgot to cancel after the first month and was told to detain 36 yuan. I called the customer service and scolded them. It's no use.
