I've also hired a maid through Betty, Professional Employment Agency 專業僱傭. Though it is 零手續費 but her service is very good. I've introduced her to several BK mums by sending them PM and I've also introduced her to my own friends and their comments are good.
I heard too many many terrible experience at BK regarding poor employment agencies and I just want to introduce a good agency for other mums because I did try her professional and efficient services. I am still very very thankful to her great help until now. If you want to know my story, I can tell.
I think it's OK if any mamas/papas have any good experience with their agencies and recommend them to other BK members. It's better than searching round and have no ideas which one is good.
But of course, there would be loopholes that some real agents registered as members to pretend they have good agents (themselves) to introduce. It's hard to avoid.
I agree with MeiMeiM, if they are agents, they should say so, let BK members judge themselves.
