Indian Oil Corporation [IOC] — excessive delay in delivery just for the sake of of extra money

For coupon no 102741, cylinder delivery was scheduled on 16 oct 18, as per message received in registered mobile, my old parents are living alone in home, delivery boy named shivam was saying " extra paise do toh jaldi se delivery kr duga ni toh aise hi aayegi, even my mother has given money 20 rupees for bringing cylinder in first floor but he said : muje aur paisa degi toh turant kar duga delivery ni toh aise preshan hogi next time. Tody is 31 oct cylinder is not delivered neither he nor service agencies are resolving such problems. Even phone is not being attended

So please help us, and punish such miscreants those are defiling the name of gas agency

Thank you
