Indian Oil Corporation [IOC] — fraud in petrol filling and the amount taken

Address:

Hyderabad, Andhra Pradesh, 500081

I asked the guy to fill petrol worth 500, and I said it loud and clear. He just filled 100 and stopped. I thought it's by mistake and asked him to fill 500 not 100, he said ok and started filling again without resetting the meter and thought I did not notice, he then asked for card, fill pin etc. so that I get distracted and nicely said 500 done when the meter just reached 400. On questioning he said that he filled 100 before and 400 now so the total is 500, when I started arguing he simply said "ohh I forgot to reset and filled the remaining 100". When I thought about it I realised he stopped at 100 for the two people ahead of me as well. Just imagine the level of fraud these guys are up to and they are nicely cheating innocent people !! Mathematically the numbers would be huge, 100 * maybe 2k ppl a day = 2 lakh / day.
