There is no text message reminder for CCB credit card refunds to merchants. Because the refund is initiated by the merchant, the CCB system cannot send text messages for this. Generally, after the merchant's refund is successfully processed, you can check the credit card bill status in about 2-3 days. There will be a refund record, and the transaction description will have the words "Refund/Return", or the date and merchant name. You can search "China Construction Bank" on WeChat, follow and bind your credit card, and check the refund record of outstanding bills.
