Indian Oil Corporation [IOC] — Air filling facility is not available at the gas station and receipt not provided.

Address:

Indianoil-Adani Gas Pvt Ltd CNG Station shikarpur Bypass rd Upper Kot Bulandshahr Uttar Pradesh 203001

Air facility is not available at the gas station.
After fuel filling at 3 sep 2022 approximately 7.30 am. I asked to fill petrol of 300 hundred but at first the employee filled only filled for 100 then when i asked again he filled fuel of another 100 but didn't set the meter at zero second time so he filled fuel of 200 only in place of 300.
When asked for air filling and receipt he denied.

I would like to take strict action against this and want my refund.
