The staff is extremely rude. I called to ask for more details on the course, the reception hang me up 3 times without saying anything. And finally at the 4th time he asked me "never call again, no one can speak Cantonese here". I am really pissed as he can simply ask if I can speak in English instead of hanging up without a word. I will never consider their service and I highly recommend them to update (English only) next to the enquiry number on the website.
