Max Bupa — Refund not done for health insurance policy cancelled three months back

Hi Sir,

This is to bring into your notice on the challenge that I am facing with Niva Bupa in getting the refund done for the health insurance policy (Niva Bupa Health Insurance Certificate No. )which I had closed on 1 Dec 2021.
Despite sending multiple follow ups I am not getting any response nor proper resolution.
Could you kindly look into this issue on priority and help in taking this to closure.

I am not getting promt response form Niva Bupa officials to the multiple emails, follow ups and grievance channels where I raised this complaint.
I am told on 20th March that refund is credited and to check my account.I am not sure if I am being cheated since I have not got my refund amount credited to my bank account
I had submitted all my account details along with cancelled checque and 3 months bank statement to an official, renjith.[protected]@nivabupa.com.
I have sent multiple mails to him asking to confirm if the documents have been shared with concerned officials of Niva Bupa but he has not bothered to respond.
Can someone please look into this at priority.
I have interacted with multiple health insurance providers and this is the worst experience I ever had where I dont get response to my emails or calls or the online complaints raised via grievance channels.
