Nayara Petrol Bunk - Diesel instead of petrol

I am regualrly using nayara petrol bun for refill of petrol to my car TN ** CK ****, but last Monday i.e. March ** **** around * AM IST has filled diesel even though I have said petrol. I have started with available petrol towards office, later car has stopped and its not moving. So, booked towing to car showroom and came to know about this. Later I tried to reach petrol bunk owner by using invoice bill which has incorrect number on it. Later by March ** i have said all those details but owner of petrol bun denying. So i have complained nayara customer care also, where they is no response so far. Planning raise a complaint against Nayara and Petrol bunk owner.
