濤兒,
Calm down~ You've better to discuss with your 99 and warn your maid. It's only the first few months she is in HK. You've to plan if she doesn't improve then you bear her or fire her lor~ But I can tell you 100% maid will tell lies!
濤兒,
From your message, I think your maid is lazy lor~ You may warn your maid that if you heard anything from your 99 again, she will be fired. Let's wait if any improvement from your maid~
