Domino's Pizza — bill related

Address:

Food courtno. 11, 3rd floor, Brookfield Mall, ITPL Main Road, Kundanahalli, Brookefield 37, Bangalore, Karnataka

The bill amount of my order was ₹580.34. I had enough money in my card. They swiped my card twice and said it gt rejected. So i paid the bill by cash. When i checked with my account, the bill amount was debited twice. Only one time the money was credited back. The salesperson assured me that i will be credited soon. But its been more than 5 days. And i am residing in coimbatore. How could i go back to bangalore and get my refund?!.
