Star Health and Allied Insurance - Bluff in renewing policy of my father

This is to inform you that I Rehan Ahmed applied for the health insurance Policy No. (P/******/**/****/******) of my father named Mr. Riyaz Ahmed of sum insured of Rs. * lakhs from Meerut branch through the agent named Sanjay Gupta in the year ****, at that time this policy was under the category of Family health Optima insurance plan in which my younger brother was included. In the year **** I renewed that policy by paying its premium. In the year **** my younger brother named Sameer Ahmed excluded in the policy and I continued the policy for my father only for which I filled a separate form and paid a premium at the Meerut branch personally by the Punjab National Bank Debit Card of Amount Rs. ****/-(POS ************ in the name of Star Health) on **th April **** but I have received a same policy bond of the year **** in ****. Today on *th April **** when my father visited the Meerut branch and he came to know that there is no policy issued or renewed on his name for the year ****. I confirmed it with the customer support and they also denied with the new policy record for the year ****. This shows your casual attitude towards the customer and you people are so careless about it. So tell me if any mis happening had occurred during that period who was responsible for that, I need a compensation for that. As far as I am concerned I have a set back by knowing this whole bluff. I have filed a complaint on NCH with docket number ****** but company had replied that insurer did not informed earlier but i already mailed them on */*/** before policy expiry date which is **/*/**.
