United India Insurance Company [UIIC] — mis guidance in settlement of medical claim no:[protected]

Address:

Kokkiligadda, 521125

I'm corporate medical insured from 5 years. Policy no:[protected]p[protected]
Claim no:[protected]
The present (Hi tpa) customer care guided me to claim in domoliciary format (After listening my treatment done). I did same. But claim was simply rejected with reason:"treatment not come under domiciary". Again customer care told me that it should be applied in normal claim (Part - a and part-b forms filled). I already told 1 day (24 hours) patient was treated in hospital and referred for some other doctor and some medicine bill lost. They guided me apply in domiliciary. Now i had sent part-a, b application. They are telling it was not received. I cleary mention in hand wriiten letter about above said matter and attached with domiliciary format. They have not read n rejected simply.
Please take consideration for better process
