China Merchants Bank sent me a short message with a credit card saying that my fixed quota would definitely be raised to 15000.

After receiving the SMS from China Merchants Bank to increase the fixed amount for customers, as long as the cardholder does not refuse, it will definitely increase the amount for the cardholder after the time indicated by the SMS.

Generally, you will receive a promotional message with a fixed amount, which reads: "XX will increase the fixed amount of XX (name) to RMB. If you don't want to accept this service, you can reply to the text message "XXXX" before XX months to express your refusal. If the cardholder doesn't refuse, don't reply to the text message, and wait until the date in the text message to check the promotion amount.

Cardholders can also apply for a fixed amount of promotional activities. The application for upgrading the credit card fixed amount will be comprehensively evaluated according to the information attached to the cardholder's application and the specific situation, and then the cardholder will be informed of the audit results.
