Max Bupa — Refund Claim Rejections

I happen to purchase Niva Bupa Insurance personally last year. This year I was admitted to a hospital for Covid. I usually visit only 2 hospitals and I made sure that Niva Bupa had time up with both the hospital but ended up as a surprise that their association with the hospital has come to a pause.

I had to start my refund process the moment I was out. I was tormented by their process. Now, I have no clue as to why my claim has been rejected; I called to follow up with customer care and I get this info. No official mail as well so far.
