Tata Consultancy Services — Repudiated - Awaiting insurer concurrence even after provided all documents

Hi,

Not sure, Even after providing all documents claim[protected] status is Repudiated - Awaiting insurer concurrence

I have platinum plan for myself, father and mother . Unfortunately, My mother was infected with covid in may 2021 (peak time of covid where getting bed for treatment itself painful and very expensive at the same time) we have tried all our best to save our mom . she battled and left us on may 8th .

Its a very big shock for us because everything happened when we are in the process of trying to understand what's happening .
Her vitals are stable and suddenly she started feeling difficulty in breathing and saturation levels were dropping that's when we took her to hospital .

I have uploaded all documents...
-- Final bill
-- pharmacy bill
-- All tests performed on each day
-- Advance bill
-- death certificate
-- Doctor letter (advising patient is not in a state to take scan but rapid test do confirmed its covid ) as a discharge summary
-- vital chart
-- case sheet
-- drug sheet
-- oxygen supplied doc

Even there is no explanation on why its in repudiated state . The documents are clear and valid . watelse is required is not sure .
Seriously frustrated ! And also im not able to reach 1800 number from australia . Tried several times with different patterns but the result is the same .
