Genins India Tpa Ltd — Denial of Claims and Unresponsiveness on queries

I have been a victim of Genins India TPA Insurance Company Employees - un repsonsiveness.
I have treated my Father for COVID criticality in a non-network hospital and have submitted all the bills for claims.
After that, it took nearly months for them to respond and clear the bills after a hell lot of queries.
After 4 months, Genins reimbursed me not even 1/3rd of the claim amounts.
When inquired, there was no response to emails and calls - was utterly frustated.
After several escalations and contacts through United India Assurance friends, I got the claim processing executive number and he too responded saying "how you got this number?", when all they did was to not just attend the calls!
After discussing with him, he clarified that the hospital has charged you more than the state govt. notified charges and we have reimbursed the charges as per govt. notifications only and nothing else to explain.
I had a detailed discussion with one of my friend in United India Assurance and they explained me to submit some letters and forms to the Hospital, Genins & State Govt Health Authorities Grievance Cell for claiming the excess amount charged by the Hospital.
For which, I had been writing to Genins for nearly 2 months now to give me the State Govt. notification and the charges approved and rejected based on that for reference and further process - and till date nobody is responding to that!

All that i understood was - Genins TPA is the worst customer facing company and only motive is to loot money in name of premiums (my reimbursement was not even equivalent to the premium - i have paid for the insurance coverage).

I will make sure that a proper addressal is been made to the Company executives for such a treatment on any customers, when you generate revenue only through them.
