Christian Medical College — No estimation has been provided and phone disconnected on face

This is to inform you that my brother, Soumyadeep Nandi( Patient id-667153H) is admitted in CMC vellore's covid ward. He was first adviced to stay admitted for 7 days( henced we booked a private ward) but now due to his health conditions it has been extended to 21 days. I have called them to know the estimate amount because there is a certain amount till which we can afford. Nobody is helping us and doctors are disconnecting calls. I HAVE COMPLETELY LOST FAITH IN CMC VELLORE now because the service and communication is horrible. Should I assume that excruciating money is part of the business and hence no estimation has been provided? We are not billionaires and hence each penny is precious for us. We have to plan things so please help us with an estimation so that we are not surprised by a bill of huge amount when I discharge my brother.
