Indian Oil Corporation [IOC] — Regarding cheating from oil pump workers

Address:

Bahraich-Lucknow road, Bahraich, 271201

Sir/Madam, today at 8:00am, I went to one of your petrol pump on Bahraich- Lucknow road, Bahraich, UP- 271801, to get some petrol but i noticed something unusual there.
First of all, i don't know why, but he completed the whole process of petrol filling in two attempts. I demanded petrol of price 1, 500 but he first sets the pump at 496₹ then for 1, 004₹ and when asked he just blabbered something.
Second thing i noticed that he was not locking the pump handle but dripping the petrol, even after telling him to just lock the flow.
This is not the first time I'm dissatisfied from your service. Please take some action regarding this. Thank you.
