I think it's a text message to cancel the quota.

Generally speaking, the credit card promotion quota can be divided into temporary quota and permanent quota. If the credit card user is temporarily unable to withdraw cash or the temporary limit is not enough, he can call the customer service phone of China Merchants Bank after repayment to request an emergency account cancellation, or solve the temporary problem. In addition, China Merchants Bank will give cardholders with good records a temporary quota of 20% during major festivals.
