Their customer service is by far the worst ever! No email replies ever, their chat system is appalling, nobody answers the phone (not even their international line), and good luck if you don't speak Chinese! Even their international websites are in broken English, have broken links, or show messages in Chinese, even though you're on an English website. No luck trying to check in from their website either, and the app is just useless in any other country other than China. All in all, THE WORST!!!!
