This is about the Hindustan Petroleum corporation limited, which is located at plot no 2&3, survey no 109 to 111, chaitanyapuri, Gaddi annaram, Hyderabad(which is taken from google maps).
today morning(i.e, 03/08/2022 at 9:00am) I went to petrol bunk as mentioned above, I asked for 500rupees petrol, but he filled for 100.62₹, then i asked him to make it for 500₹.
He didn't even made the machine reading zero, although he started from 100.62 and filled up to 398.8 or something change lessthan 400, he charged me 500₹
This shows that the bunk in capable of keeping the proper working machines which is located on national highway, and improper workers.
so please take some action on this incident.
thank you
