the manager told me how he dosnt care

I went to put fuel in my car, after the petrol attendant who was helping, tells me that he did put petrol in my car but i told him who my gauge didn't move and every time after i put petrol it moves, then i asked for the manager after arguing with the guy, the manager didn't wanna come so i went to him to explain what happen as this is not the first time but he told me how he doesn't car about my petrol gauge, my car and i must just pay
