First of all, sorry for the inconvenience. I've just called the number on the page and confirmed that:
* The number on the page is indeed only in Mandarin, and * They don't offer a number for English service, at least not in the knowledge of the people who took the call. I'm not a member of the local team though, just FYI while I edit the page for good. 林博仁(Buo-ren, Lin) buo.ren....@gmail.com
