The monthly interest on a China Merchants Bank credit card is approximately 150 yuan. This is calculated based on a loan of 10,000 yuan with a daily interest rate of 5/10,000 yuan, that is, 10,000 yuan × 0.05 × 30 days = 150 yuan. If you choose the minimum repayment method, you may need to pay more interest and cost. China Merchants Bank's Credit Card Customer Service Center was named "China's Best Call Center of the Year" as early as 2004 at the China Call Center Operation and Customer Relationship Management Conference, and is the only award-winning unit in the domestic financial industry. In 2002, China Merchants Bank realized integrated and professional credit card services.
