Hi chenyiru,
Thanks for your post and welcome to the forums. It's great having you on board with us in the Community although we are sorry to hear you're having an issue with getting a service while abroad.
We'd like to take a closer look at things for you although to do this we'll need to pass data protection. I have sent you a private message regarding this and will investigate further once I receive your reply. Just click on the little plum envelope at the top right-hand side of the page to access your inbox.
Thanks,
