Manipal Hospital — Not doing refund for non consultation

I wanted to consult gastro doctor and got appointment online for dr sreenivasa d. After waiting for half an hour on computer meeting room, i disconnected as doctor was not available. Since then, its 15 days and i am asking refund for this, they have failed to do refund. Kasturi from customer care was available and she made couple of false promises after taking account details but no action.
