IOC Petrol Pump - Cheating at Petrol Pump

I have been at IOC petrol pump opposite to anand vihar New Delhi on Friday 17th August 2012 at about 10:10 pm. I just requested the staff to to do fuel tank with full, i was continously watching the meter and everything was ok, but the staff man just distratcted my mind saying that my tyre has a nail in it, I just bend a little to see, he just did some signals to another staff standing near the machine from where petrol was being filled into my car, as i went back in about 10 seconds, he said your car is full and you need to pay 1815 Rs, I asked him to do complete 1900 Rs, he said it is not possible as the car has do a autocut, while I was very near to my car, but could not listen to any sound of autocut, and I requested him again to fill upto round figures as i dont have the change, also I wanted to check if he has done something. But despite all this he just forced me to pay the amount and leave, I asked for the bill but he refused that their bill copy if finished. Even I could see that all the staff about 8 persons are accumulated at same place and asking me why I am not moving my vehicle. It was a tragic experience for me, however when I started my car, I could see my fuel indicator was not at the full status , it could be full aith the amount I paid, as normally my fuel tank is full in 24 Rs and my car was having good petrol of about 700 in my car already.

I would like to request to check with dealers despite of so much hike why these things are happening. In fact I feel pity for those who just keep sittiing inside car and order for fuel filling. I was taking petrol from the station since 5 years, and now I can understand that how much he had done similary in past as well.

Please investigate.

Thanks!
