Indian Oil Corporation [IOC] — petrol deduction during car tank filling

Indian oil petrol pump on bazpur doraha, u. S nagar, uttarakhand always fill petrol without entring amount in fuel machine. I told them to fill 420 rs petrol in my car but they did not enter amount in machine, i complained about it but that person was not serious about it, i clicked photo of it in which he filled 420.29 rs petrol, this 0.29 rs variation is due to non feeding of amount in machine.
