Mcdonald's India — about refund of money

Address:

New Delhi, Delhi, 110016

On sunday evening (20/7/2018) at dlf mall, saket, i ordered two mc veggie with extra cheese and one coke. The total amount of the bill was 315. I swiped my atm but i didn't get the receipt so i did it once again but the machine didn't give me the print. The staff present their said that the card is not working, so i used another card for the transaction and at last the bill got printed from the machine. The problem is i have swiped 2 cards (1st card twice and the 2nd one once) and money got deducted each time. I showed the transaction sms to the staff and the head told me that i'll get the refund within 72 hours, but till the date i didn't get any refund money. My bill was 315 and the staff took it thrice (Total 945). That was not my mistake so i want my money back at any case. That place is very far from my place and i am unable to go there once again and i told the staff about it but he said that the i'll get the refund at any case.
