China Agricultural Bank sent me a short message. I don't remember opening the information service. It says my balance is insufficient. What should I do?

Maybe the landlord didn't notice? Now that I have informed you, it means that this month's expenses will be paid, at most two or three yuan, maybe four yuan at most.

This month's payment has ended, please contact customer service to cancel this service function.

If you don't pay it, it will probably be considered overdue and the consequences will be very serious.
