But don't say that you didn't do it yourself. You leaked the credit card information and issued it.
in fact, there is no fraud, that is, the staff who called you are unfamiliar with the business or refuse to accept responsibility. Since you said you would cancel the installment, they didn't give anyone any explanation. It's definitely their problem to count 12 installments directly. Just bite this point. There is no problem at all. They made a terrible complaint. After all, it's a bank. After all, it cares about its own reputation. After all, it's a regular unit. It makes sense. Don't say it's operated by others. If you have said it, it's your child who is naughty and is under your supervision.
By the way, if you want to complain, you should complain to individuals, not to the management regulations. The regulations are unshakable and legal. It's a waste of effort. Just complain to the qualified people who call you, tell them the phone number and the time to check the recording themselves. The final result may not be to exempt you from the installment fee, but you should fight hard and remember to be tough and lose your temper. At least I can give you a cheaper handling fee. If there is no way to change it in the system, the final result may be that the reviewer will pay for it himself. Have I made myself clear enough?
