Bharat Petroleum [BPCL] — Rude behaviour of petrol pump guys.

Address:

MSW*TIRUMALA FILLING station, Pragnapur, Medak, Telangana, 502311

I came to Tirumala Filling Station Pragnapur Medak district Telangana, to fill petrol in my tata Nexon petrol car but the attendant filled the tank with diesel, after going some distance my car broke down I got the car towed and brought it to garage. When I asked the bunk manager he verified it in Cc tv an confirmed their mistake.
After i informed him about the mechanic charges he refused to pay the full amount saying that it's too much and started to bargain with me, i even offered to pay half of the amount of towing and mechanic charges. A friend of bunk manager threatened me saying that take the amount they are offering or do whatever I can and they will not give any more money.
I had to shed amount from my pocket as they were threatening me.
