Powder is quite right that you cannot quite link. Look at your initial post. What is the question? It isn't a query asking for sharing of others experiences with maids. Rather, the process of getting a maid and how much it cost.
If your concerns are abt bad experiences with Maid agencies, you should be asking abt things to look out / avoid for when selecting and interviewing the maid. Also, what are the black listed ones etc.
When you ask the wrong questions, expect the wrong answers.
If your friend is leaving the maid at home to be alone with the kid. Its could be risky. Do install CCTV and religiously monitor it. Having the CCTV alone is not enough as a deterence. After sometime, when she figure out that the CCTV is not monitored, the maid will get bolder despite having her criminating acts recorded.
Many maid agencies will recycle returned maids even with really bad history of cheating, stealing etc. Their reviews on the maids they place on their websites isn't reliable at all. You need to interview them and make your own judgement from their body movements and response. No one else can make that selection process easier for you.
One of the maid I sent back, wore our clothes, ate our foods with very poor hygiene, she licked dry the knife she spread the peanut butter and place it back in the drawer with the rest of the cultery. Drank water directly from our water pitcher, scoop our soup daily directly while still preparing, try all our dishes directly while MIL is bathing after cooking, act stupid and slow to avoid cooking and helping in the kitchen, finished our expensive ice cream, litter used empty containers of food out of the window to avoid detection from the trash, stole money by denomination of $50, sneak out daily for breakfast and snacks. Butter trade her shopping snacks with neighbouring maids, changed openly in our kitchen while we were in bed. Pretended to work throughout the day but idle the very second not in our view. Took every opportunity to call back indonesia using her calling card with the money she stole. On the average for 2 weeks that we monitored her, daily calls are longer than 45 mins to hours. Turned on the iron to pretend to be ironing laundry when we are out and only go back to the ironing board when we return hours later.
All these were caught in CCTV.
