If the cardholder does not take the initiative to apply for a reduction, the credit card will inform him when the reduction is made. Credit cards will be reduced because the cardholder is overdue or cashed out, so before reducing the limit, the bank will also inform the suspect of cashing out, and may take measures to reduce the limit, or warn the cardholder to repay as soon as possible. The reasons for each reduction are different. It is usually a SMS reminder within one to three working days. If there is no reminder, you can call the customer service phone of China Everbright Bank to ask.
