do u hv the receipt? if yes, take it and ask for refund. if no, it's really hard to do so.
(may be u can ask someone to accompany u to go to their office and wait until they hv customer, then shout to them keep saying they cheat......)of course, this is not a good method.
I do have the receipt. The 衰staff of 無良agent - Cheuk Txk 海x傭佣中心 (in Wanchai) is very bad services and not responsible at all. 教工人告僱主,告到小額錢債,仲上咗三庭. Finally, I won.
But they said they have introduced 個工人 to me. They finished the document before 請工人. So they will not refund any $$$ to me. :-|
