Subject : Cheating/Fraud at Total Petrol Pump near Jhanda Chichi Fraud
Sir,
i was going to Islamabad and was already in hurry, i felt i need to fill fuel tank,
i stopped at This Petrol Pump and asked the guy to fill the tank for rs 500/-, he started filling and stopped at 100, i said please fill for rs 500. he again started from the previous point and stopped at 400. i said don't you under stand i need you to fill it for Rs:500/- he said sir 100+400 = 500/- .
at that point i was 100% sure he is cheating, i told him he is cheating, i was in hurry so i had no time to prove he was cheating. i left the station and now when i am free i search in google and it came on top that This Station is has cheated many many people in same manner, now you have many many people's same complaint i request you to please take action, i suspect that the manager and all staff are involved in this corruption.
if you took action, please let me know.
Thanks
Regards
Tallat
