I can understand your frustration, ksy. I also think that companies could behave more professionally by replying to reasonable queries.
Whilst I agree to Shri's advice regarding the lack of professionalism in bashing previous or potential employers, I believe you are entitled to your opinion and that many share the same. You should only share that with people you trust instead of putting it out there for potential employees to see. I do note, however, that you were quoting someone and that you were not the one who made the statement.
I am sorry to hear that the job opportunities in the gaming industry in Hong Kong are few. Hopefully an opportunity will open up soon. Wishing you all the best!
