Thanks everyone for all your prayers and help.
I am afraid the experience with caregivers have been pathetic so far. We requested for 24 hours service in 2 shifts and they are simply unable to provide good trained caregivers even after paying them so much. We had to change the service provider once and the current one can only provide one caregiver even though they took money for two for the two shifts. The experience with caregivers is even worse - they have no respect for an elderly patient and are callous and untrained. They just sit and fiddle or talk on their mobiles. Anyways we will keep looking.
