If the money in your bank card is also deducted when you pay with Bai Hua, then you need to check whether the bank has repeated deductions. Another situation is that you didn't see it clearly when you paid, and you chose to pay by bank card instead of flower buds. In addition, if you negotiate with the merchant, the customer can still pay part of the money with the flower garden first, and then pay the rest with other payment methods, such as cash, Alipay balance, Yu 'ebao, fast binding savings card, WeChat change and so on.
