Indian Oil Corporation [IOC] — denied card swipe and misbehaved

Address:

sourabh petroleum, opp JK school, Dharwad, Karnataka, 580032

I went to sourabh petroleum (Iocl dealer), opposite jk school, hubli-580032 today at 8am to refill petrol in my car. On asking if swipe is available he murmured "morning itself want to use card, give cash instead" he spoke in kannada). He has given excuse that machine is not charged. I was taken a back and went inside the office wherein supervisor also argumented with me. When i introduced myself as banker and informed that i know the card processes, he has thrown my visiting card in air. Such a rude behavior.
I urge to register complaint against the supervisor posted at sourabh petroleum and should be given stern warning.
