Mcdonald's India — Missing item from Order and recharge on ordering again

Address:

Eros Market Plaza, Plot #2, Shakti Khand 2, Indirapuram, Ghaziabad, U.P. India

I had placed an order # 1228 on 5th June (Order Copy attached). One item from order McChicken Burger was not delivered. I complained and was given Rs. 150/_ voucher. I again ordered McChicken Burger via Order#1266 (order copy attached) and made to pay Rs. 60/- after applying the voucher while making payment. This is totally unfair that I have to pay extra for an item that was missed from original order for no fault of mine.
Request you to look into this and initiate appropriate refund.

Thanks
