Iifl Insurance Brokers Limited - False policy commitments

Insurance agent called me from IIFL and explained about Bharti Axa Elite Advantage. Below things he has mentioned.
Policy will be covering up to *.* lacks of hospitilaztion charges annually which includes me and my parents.
Policy term * years and on *th year onwards i will be getting bonus amount of *% of interest on sum assured(around * lacks) every year till **th year and on **th year i will be getting * lacks.
Grace period for policy cancellation is ** days.
He lied all this and i have taken the policy after one week i had received the document from Bharti Axa in that above mentioned points weren't exist so call back to agent then he again convinced me saying that they will be sending an updated document so I have waited for another ** days but actual grace period was ** day, now i can't cancel the policy
