Take China Merchants Bank's credit card as an example. For cardholders with good credit card records, our bank will increase the fixed amount from time to time. Cardholders can also apply to increase the fixed amount by themselves, and our bank will review their card usage such as consumption and repayment to determine whether to increase the fixed amount. Application method: Log in to the credit card online banking, and click Account Management → Account Limit Management → Quota Adjustment. You can log in to Pocket Life and apply for increasing the fixed quota. You can also apply by telephone voice. After calling the credit card service hotline to verify your identity, press 2 to enter "Line Inquiry and Adjustment", and then press 3 to enter "Line Adjustment Application". There is no fixed time limit for quota adjustment, and the audit results shall prevail. I wish you a successful withdrawal!
