Today 11 Nov, 2014 around 8.15 a.m, when i was filling the petrol, the two employees cheated me. I ask them to put the petrol for Rs 200 but when i was giving the money the guy who is filling the petrol suddenly stops and the meter was stopping and it was showing only the amount not the amount of petrol filled. The guy who was collecting cash was distracting me by saying CASH or CARD. what is the need of asking CASH or CARD when i m giving cash already to him. Kindly take proper actions against those people.
