Bharat Petroleum [BPCL] — Misbehaviour

I would like to bring into your kind consideration that on 04/06/2022 I visited Bharat Petroleum, Petrol Pump -Subash Automobiles OPP. LAXMAN SYLVENIA, GREAT, GAUTAM BUDH NAGAR, Uttar Pradesh 201306 for the refilling of fuel around 15:40 Hrs and I asked for a refill of Rs204 and But, the staff didn't filled the fuel and talking very rudely and said "pehle payment kar baad me bharunga" when I asked him to talk politely he said "nikal yaha se tere jese bahut aate hai" when I approached to the manager for the same he also replied in the same manner and instead of counselling his staff he is taking his side and when I asked his name he denied then I asked for complaint book he said complaint book is not available.
I believe you would consider this as a genuine issue and you would take some appropriate action as this may lately affect the reputation of your renowned fueling station. You may contact me at [protected].
