You're going back to work on Mon? Even if the agent send you the maid tomorrow, or say today at the earliest, do you think you have enuff time to familiarise her, dun say train, to baby's likes/dislikes, routine, and simple things like how to prepare her milk, how to warm milk, how to sterilise. I dun think you'll be able to go to work with a peace of mind knowing how maid will cope with baby. Will your maid be alone with bb or one of your parents will be with her? If no one is with her, i think you have to think of contingency plan. Either find a temp babysitter or ask your caregivers to chip in and help.
IMO, your agent is taking you for a ride. It adds to their cost to have a maid fly in, take the test 3 times and then fly them out???? Impossible! Agencies surely have a way to make the maids pass the test, some of 10 yr series. Who's going to foot the cost of airfare for nothing? They also have to feed and house her. It's good you called MOM. Get written evidence from MOM wrt to your case and record everything your agent tells you, better still if got written record and go to case/small claims.
