Burger King — customer abuse

I visited burger king around 9:35 pm to 10: 10 pm in the forum mall, while i ordered mutton burger then finished ordering and paid 210 rupees, he gave me 1 rupee to me, immediately i have changed my mind i did not even put the change in my pocket.in the meanwhile i have changed my choice of food, so i asked him can you change to spicy wings, but the cashier said we can not alter the order after i put it in the register. Then asked him to call the manager, he also refused to modify the choice of good i am asking. Then i was thinking of calling burger king office, and make a complaint, but before i do that i wanted to talk to the manger again, then he told the cashier to give me back my difference money for the 4 pieces of spicy wings, but that was only 40 rupees difference. When i was trying to call the burger king office, the manager decided to change the order and gave me that 40 rupees only. Ifelt that the manger did not give me the correct money, i just wanted to inform this. My cell number is [protected], my name is michael
