Reliance Petroleum — cheating by entering wrong value as input

Address:

Jaipur, Rajasthan, 302017

I visited the said petrol pump today twice in the morning and evening. First time i asked the salesman to fill petrol for 400/- but he entered 101 value and delivered fuel without showing zero. When i said him to complete the amount he started the meter from last reading without showing zero again and then he stopped at 300 and said that he has topped up for 300/- but the same day after ridden around 200 kms bike was in reserve mode then i felt that i have been cheated. Coming back to home i again visited the same petrol pump and asked for fuel for 100/-. The salesman again did the same cheating in the for of amount 30/- and 70/-.
My father told me that he also has been cheated in the same way earlier.
