Rejection of medical claim policy on false background

Dear sir I have easy health policey of hdfc life which is life insurance policy having benefit of daily cash benefit of hospitalization. I was admitted in hospital due to intestinal obstruction for 3 day ICU and 4 day in pvt room and my hospital bill was 46000/ and company rejected my claim on 3 points, frist point was that in hospital indoor record my date of discharge was different, on this point when I asked hospital they said it's manual mistake and in every document date of admission and discharge is correct. Second point was in hospital registration certificate renewal was not in claim year but when i review hospital registration certificate shows renewal stamp of this year but stamp was little bit light so this point is also incorrect. Third point was my treating dr is not RMO of that hospital when I asked hospital for the same hospital told me that my treating dr is on call basis and his name is also mentioned in registration certificate of hospital so this point is also wrong.
