Indian Oil Corporation — harassment and misleading

dear sir, It is a matter of great shame and concern that the staff of indian oil petrol pumps are mis-behaving, mis-guiding and harressing the customers. Today morning while I went to the pump for filling petrol in my bike, I saw que in one machine out of the three petrol machines. I stood near the other petrol machine for so long and then when no one came, I went to call the staff to fill petrol. As soon as i called him, he behaved so badly and insulted saying that petrol will be given through one machine only. I said I waited so long and after this much time how could u respond so badly, he said me to get lost and do what ever i wanted, but the petrol will be given through that one machine only.. The machine was in a working condition but still they all were resting and not working there. Is this the procedure to treat the customers. Their language was so hurting.. Every thing must be there in cctv which was presented in the petrol pump.. I demand and expect Severe action towards this.. thanking you
