Indian Oil Corporation [IOC] — overcharging and playing frauds with customer

Address:

M/s Autocare , court road sectorc12 faridabad, Faridabad, Haryana, 121006

I am professor dr s. K. Chakarvarti, resident of faridabad.
Today the 24th april 2019 at 11:20:49 am, i went to indian oil petrol pump auto care sector 12, sitec2 faridabad to get filed my car.
I requested for 13 litres of petrol but the operator filled only 3 litres. I asked why so? In response he told that he heard 3 litres. I said then make it 13 after bringing back to 0 reading but he continued with 3 reading and stopped at 10. When i objected to this he tried to be fool me saying that already 3 lit has been supplied. I shouted and scolded him for this sort of fraud and then he filled 3 more lit. You can see clearly how they cheat the customers. When asked his name he told pramod as his name which i doubt very much.
Further i was charged rs 950 for 13 litres which i think is overcharged as the current rate is rs 72.99.
The payment was made by debit card and the details of the voucher are as under:
Date: 24.4.19, time: 11.20.40 am
