Hello, this may be because your credit card consumption was not recorded on the day of withdrawal. For example, you just swiped more than 1 300 on the day of withdrawal, which led to the credit card transaction amount being recorded first. After the withdrawal amount is recorded, it defaults to overdraft withdrawal (the kind that does not charge fees), and the interest of five ten thousandths is deducted every day. If the interest is insufficient 1 yuan, it will be charged at 1 yuan.

On the other hand, before you deposit, do you confirm whether there is any debt in the credit card (both accounted for and not accounted for), and the self-owned deposit will only be counted after all these amounts are thrown away;

Conclusion: This situation belongs to the problem of GDB card system, because there were credit card transactions and withdrawal of self-owned deposits on the same day, but because of the different input order, the system could not intelligently identify and withdraw self-owned deposits, so interest expenses were incurred. This situation can be explained to the customer service and adjusted directly.

How to avoid it effectively: you must pay attention to your credit card consumption on the day you withdraw your deposit. For example, you had a deposit of 100 yuan on the day you applied for the card, and then you withdrew 100 yuan, but you had already spent 1 yuan that day. Credit card consumption 1 yuan may be settled in the system before your own deposit 100 yuan (not available but according to the posting time), so it is possible that the system will think that you overdraw 1 yuan in cash, thus generating interest, which rarely happens. In order to avoid this situation, you must pay attention to the credit card limit on the day you withdraw money. If there is any deduction of handling fee or interest, you can directly inform the customer service, and the customer service will unconditionally help you apply for adjustment.
