The reason for the complain is that when people go to fill petrol in their vehicle, they fill with the extra premium, we as a consumer wherever we had gone before, if we say them to fill petrol we were asked if normal or premium in any petrol pumps.
I told the worker there to fill my tank with petrol but without my conscious the worker filled it up with extra premium when i told the worker why premium the worker say nonsense reason that this line is for premium and that line for normal petrol, but when i observed all the lines were doing the same and the customers are unaware of what is happening there. I would like the concerned authority to check the matter of the date and time given and look at their book of records and see the matter and take appropriate action on it.
