Honda Cars India Ltd. — sale of blacklisted car

Address:

Ring Road Honda, Peeragarhi, New Delhi, Delhi, 110041

I purchased a used car - honda city 2014 model from ring road honda, peeragarhi (Dl4caw1402) in the month of march 2019.
To my surprise i got to know that they had sold me a blacklisted car.
According to them, this car is booked under some corruption case which they had sold me intentionally and are not ready to buyback the sale. I have been chasing them from past 5 months and have remained unsuccessful till date.
A payment of rs. 455000 was made to the dealership by online transfer and rs. 45000 was paid in cash to the dealership as token amount to book the vehicle.
Request you to kindly refund my amount at the earliest as this vehicle is not getting transferred on my name. Failing to which i will be forced to take legal actions as may deemed fit.
