Try +800 2747 2200 (or 011 800 2747 2200 from North America).
If you are in the U.S., a lot of U.S. mobile phone carriers (even if you are roaming from abroad) don't support toll-free International +800 calling. Works if calling from Canadian mobile phone network though.
However, if you can borrow a traditional landline (non-VOIP), you can dial 011 800 2747 2200 for free to reach the HK call center.
