I too had a similar experience, the maid he sent us was old and had Tuberculosis on top which is contagious.
The maid stayed for about 2 weeks, by when he encashed the cheque and then she disappeared.
When we called him he started blaming us for not keeping the maid properly.
In Bangalore this is a huge racket, no body should go through these thugs, in that way day-care centres are more reliable, but again they charge a bomb becouse of all these issue
