Bharat Petroleum
Cheating at petrol pumps

There are many petrol pumps in Jaipur, whose workers divert the attention of the customers and start filling the petrol in the vehicle. This has become very normal in all petrol pumps so people now are more aware of this. But this is not it, these people have also managed to do something with the machine so even if they start filling petrol from zero, petrol will be less. This thing has created a sense of fear which you cannot help even being alert does not help this issue. Please tell me what should i do???
