Advaitha petrol pump cheaters
I filled petrol for 300 and told to add additional for 30 and later I told to add additional for 30 rs...but the guy told he added for 70 and now tank is full when I told that to add for 30, he told that I asked him to put for full tank then manager came told no one can cheat and manager started supporting his worker, actually Honda Dio capacity is only 5.3 litres but as per their justification they have added 5.6 litres...cheating with Bharat petroleum whom to complain...God save us
