Address: 201310, Amit Nagar, Pi I & II, Greater Noida, Uttar Pradesh 201310
Date of incident: 16th October, 2022.

I went to fill petrol in the petrol pump with address mentioned above.
As I was entering, I was led to premium petrol pump. I was told normal petrol is not available. I thought the premium petrol normally is around Rs 5 more per liter than the normal one, which is fine. But this was X100 which I had not even heard about till that time. When I saw the price on the meter, I thought it was some kind of mistake on display. Just to be double sure, I asked for the price of the petrol. But the attendant wouldn't tell me. He went on to start filling the petrol, and then he told me the price which was Rs 160/liter. I had to shout to stop him from filling more, otherwise he just wouldn't stop. After this he told me that normal petrol was on the other side.
All I wanted was to fill normal petrol in my normal car. But this is a sham/scam going on in this petrol pump. I am pretty sure, I am not the only one who was tried to be duped.
