The credit card of Industrial Bank suddenly dropped, and no message was sent.

Hello, I would like to ask if Xingye's credit card was suddenly rejected and no message was sent. Industrial credit card suddenly reduced the amount and sent a message. The precursor of credit card downgrade is that it will give a warning message. After the credit card is downgraded, it will send a message to tell why it is downgraded, or directly remind it to downgrade, so Xingye's credit card will suddenly downgrade and send a message.
