Hello, you can return the US dollar cash when you return the US dollar. However, if your credit card only has a RMB bill, the returned US dollar cash cannot be repaid. It is suggested that you re-consume this US dollar bill, or take it back as overpayment (the handling fee will be deducted when you get it back).

You can consult any credit card service information of China Merchants Bank online through QQ or WeChat. Method 1: Search 4008205555 among QQ corporate friends, and add China Merchants Bank Credit Card Center as a friend; Method 2: Search "cmb4008205555" on WeChat, and pay attention to China Merchants Bank Credit Card Center.
