Essar Petrol Pump — 1. Attendants not waiting for Auto Cutoff. 2. Rude behaviour

Address:

Harsha Enterprises, 3037/2597/3, Gottigere, Bengaluru-560083.

I have been a regular customer to Essar for several years. The main problem is that every time the attendant has to be informed to wait for auto cutoff. Otherwise, the attendant will lift the gun in a hurry as soon as the counter shows the reading. I have also lodged a complaint couple of times. But there has been no response.
I filled 10 litres of Diesel today morning vide Receipt no: J0209, FCC ID: [protected], FIP no. 03 at Harsha Enterprises, 3037/2597/3, Gottigere, Bengaluru-560083.
But before I asked him to wait for auto cutoff, the attendant hurriedly removed the gun and argued that I had to inform him earlier and was very rude. I then approached the In-charge there, but he was even more rude and shouted that they are not our slaves and they cannot wait till auto cutoff as it takes around 2 minutes. When I told him that if they cannot wait till auto cutoff, then I will not be visiting again - for which he told that he is not bothered. I know that one customer's business may not effect their business.
Is this the way the service to be provided to the customers?
This happened at Harsha Enterprises, 3037/2597/3, Gottigere, Bengaluru-560083.
I am totally upset with the rude behavior of the staff there and they are very arrogant.
In this context, may I request you to instruct them properly and have this issue corrected failing which, I will be constrained to approach the Consumer Forum to redress my grievances.
