Vasan Eye Care Hospital — rejection of service after payment of the bills

I'm john paul from theni. I visited vasan eye care hospital on 11/5/2018. The patient was admitted for eye surgery, and after paying the bills we asked for the receipt. They denied to provide us the receipt and are refusing to carry out the surgery, they are asking to leave the hospital along with the patient. And when asked about the customer care number, it wasn't given by them.

Such rude and inhumane behaviour, where the patient is refused a surgery after paying the full bill amount.
