When the rural commercial bank withdraws money from the ATM, it shows that the transaction is invalid, and then SMS tells you that the money has been spent? What's going on here?

As long as the operation is invalid, it is definitely unsuccessful, that is, your money has not been deducted. SMS can't be completely combined with the cabinet system, that is, you generate SMS after a certain step. If you don't believe me, the money will never be deducted. I'm telling you, if the cabinet had this problem, it would have become a broken machine under maintenance. Any operation without prompt is unsuccessful, which means the change of counter account.
