Respected sir
I ordered pizza from Domino's Bareilly on 26, aug 2022, which is located in phoenix Mall, bareilly.The cost is around Rs350 but due to non functionality of gas pipe line they cancelled my order.they told me that we could not refund you because I made payment through UPI..The store manager told me that your money will refund within 7 days..But it's 10 sept now my money is not refunded and they didn't give proper reason and proper reply to me..i want my refund back as soon as possible
