Max Hospital — Billed but doctor was not available. Refund still not received.

I paid the consultation charges but the doctor had left by then. So i asked for refund of the amount paid. Mr. Shekhar & Mr. Harish asked me to share my pan card, aadhar card & bank account details via WhatsApp on Harish's number ([protected]). However i still haven't received the refund amount of Rs. 800. Kindly help to resolve the issue at the earliest. Also take stringent action against the two staff involved for harassing me.
