Indian Oil Corporation [IOC] — Metal dust in petrol

I used to refuel everytime from Indian oil for short and long drives. Never had a problem but this time it gave a terrible damage to my brand new car. My last refuel was on 29th January and while driving i noticed a sudden acceleration drop, im shocked to see that performance of my latest car. so i took it to the service center and after a deep inspection they found the black metal dust in the tank which caused damage of fuel injectors and fuel pump, they are asking me to replace them as both are totally damaged and gave me an estimated bill of 22000inr. I am all upset. I started a very good day but after refuel in indian oil i get into unnecessary trouble which impacting the car, went into a major repair within 2 months. I need Indian Oil standby and take the responsibility of Loss happen to me. Hoping for a positive call back from team.

Thanks
