Bharat Petroleum [BPCL] — Giving less petrol

Address:

New Delhi, Delhi, 110026

I went to my nearby BPCL petrol pump near Rampura Red Light. He started the Meter with reading already showing Rs 50. He started telling me about some petro card. I told him that the meter is not at Zero. He didn't listen. I stopped him went to the manager to complaint about this. I asked him to give me complaint register as I want to lodge a complaint. He told me not to file complaint and was ready to fill my bike tank without charging any money. It is the second time within 10 days that this has happened. Last time I didn't filled complaint as the person starting begging for his job. I want that action should be taken against this petrol pump as the manager ( person who sit in the office ) knows everything and is also involved in this.
