@Dung Kul have you cleared the cookies and cache of you web browsers. Sometimes, your web browser's cached data or cookies can interfere with the payment portal. For good measure, I also clear my history as well. Try clearing your browser's cache and cookies, or try using a different web browser (e.g., if you're using Chrome, try Firefox or Edge). It's also worth trying to update your payment information in an "Incognito" or "Private" Browse window.
