Shell India — I'm complaining about bad behaviour from the staff

Address:

Mysore

Today I visited the shell petrol pump located in hunsur road mysore, where I filled 3.5 litres of V-power petrol in the scooter. Then the staff swiped more than 4 times and then she said to swipe in the office. when I came back to my home, I checked the bank statement and I found that the petrol pump has deducted 2 times and 2 different amount, one was 330 rupees and 338 rupees. After noticing this I went back to the petrol pump and asked about it in the office, and one of the staff started to mentioning that it was not there mistake but the bank problem. But I asked how can you deduct 2 different amount for a single refill. Later on, he started to misbehave. Please take neccesory action against the staff and the agency.
