Indian Oil Corporation [IOC] — Staff misbehaved along with owner (sardar) directed them to take out rods to hit us.

Sir, I, refill diesel (₹500/-) in my car from Harjap Filling station. Ludhiana, Punjab.
1. Staff person after filling oil he did not close the oil cap of my car. My brother close oil cap of our cap at petrol station.
2. After filling oil we came out from Oil station then my car's digital metre as well as another metre of car does not show that fuel is filled. We stopped outside the filling station for 2 minutes so, that fuel gauge will show fuel in our car but after that we entered our car in fuel station for conversation. After Lil' conversation Manager asked to check my car . I give him permission to check. He says that there is no problem in our filling station your car will definitely go certain meters. But i says if car doesn't go then he says you guys taken out oil from your car to cans. Within 2 minutes. Then conversation goes in wrong direction. Staff misbehaved (Harjap filling) Turban Owner said to staff to give him rod and directed staff to take out rods and other weapons. To hit us badly then we also says do whatever you want to do.

So. My main concern Is i didn't get full fuel of ₹.500/- they have cheated and staff didn't close my fuel tank cap. 2nd they misbehaved/abuse all staff and directed them to take out rods and other materials to hits us. You can check your oil station cameras.
I need strict action against oil station.
They cheated us and misbehaved.
