Max Bupa — Refund of money for Cancellation of Application No:[protected]

I applied for a Health Insurance (ReAssure) in MaxBupa(Niva Bupa) on 19th Nov 2021. I did the payment. However, due to some reason I applied for cancellation on the same day.
I sent multiple mails to support team, there was no response. I sent multiple mails to Grievance team, they are useless. They did not resolve the issue.
Then I raised complain in IRDAI, after 14 days they said they would provide me refund. It has been more than two months, still I am struggling for my money.

My IRDAI Token number:[protected]
MaxBupa follow up token: 7595032

There are other multiple tickets raised: 7377025 , 7348636, 7357456, 7379894, 7379896, 7407262 , 7379894
But there was no support, no response, no resolution from MaxBupa (Niva Bupa) Team.
