Hospitalisation claim rejection and policy cancellation from Health Insurance Co

My mother has Senior Citizen Health Insurance policy on Feb, 2016 and her hospitalization claim for Respiratory ASTMA disease and Hypertension was rejected from the Health Ins co. stating that she had Heart disease as per 1999 discharge card. The Respiratory disease ASTMA, Hypertension and Acute Calculus Gall bladder stone was already declared 2016. While purchasing the policy Star health insurance representative told us to declare the existing disease of my mother during the near proximity purchasing the insurance. My Mother had only Respiratory disease, ASTHMA, and hypertension during the near proximity in 2016 and she didn't had heart disease and these existing mentioned in the latest hospital discharge card in 2006, 2019, 2022 and 2023 that my mother is suffering from Respiratory disease and Hypertension since 20 years. My mother has been renewing the policy since 2016 and till date and it was my mother's first claim. In the current health renewed policy document and IRDA pre-existing disease guidelines it is mentioned that " As part of Guidelines on Standardization IRDAI has already defined Pre-Existing Disease. A Pre-existing disease is defined as under (reproduced verbatim). Pre-Existing Disease means any condition, ailment or injury or related condition(s) for which there were signs or symptoms, and/or were diagnosed, and / or for which medical advice/treatment was received within 48 months prior to the first policy issued by the insurer and renewed continuously thereafter." My mother didn't have Heart Disease within the 4 years of the Health Insurance policy in 2016 and from 2000 till date, She has been suffering from Respiratory Disease ASTMA and Hypertension since 20 years and it is mentioned in the discharge summary from 2008, 2016, 2022, 2023 by our family hospital doctor.
