Why did Taobao refund the bank, but I didn't receive the SMS notification?

The SMS notification of banks needs to be customized, and many banks charge fees. Other banks will notify by SMS only when the balance changes beyond a certain threshold. If the refund falls below this threshold, there will be no SMS notification. For example, if the balance on the card changes more than that in 500 yuan, the bank will inform you by SMS. This refund is only returned to 400 yuan, and the bank thinks that the balance changes less than 500 without notice.
