I'm also looking for a maid for past few weeks and had not got very good experience with the agencies.
Nation Maid : called the hotline and told them of my requirement, they just simply reply "Oh we dont't have one now" and hang up.
Jack Focus : communication was good but actual action never happen. Had shortlisted 2-3 maids and they committed to arrange audio or video conferencing then MIA. Tried another person and she's worst, suppose to arrange for meet up of a tansfer maid and end up never call also.
I'm super desperate after talking to so many to just hire 1 maid! Hopefully someone can reply to this thread and recommend a good agency.
