Generally, it's useless to look for customer service when you're in the wind, and it's not useful to look for anyone else. If you're sure you've got it wrong, you can provide your credit card and purchase invoices to the bank. Being wind control is nothing more than using the card irregularly, such as set X, swipe the card irregularly, overdue and so on. You should try to avoid this kind of situation. I hope to help you, hope to adopt, thank you.
