See this thread at 3Hobby. If you follow the thread (its not long), you may find hints there on how to check HK Post as well as how to file a complaint and what to watch out for.
Thanks for that, We should always be carefull in ordering in HONGKONG Sites.. we should know which sites are reliable and not, i think someone should put a list of some HK websites which has a good service better than the other that has mentioned.
