Coffee Day Global Ltd. — Took Double payment of 680 INR

The Cafe coffee day @ Kasturinagar Bangalore charged me twice for the same bill for 680 INR saying that the UPI transfer is not successful. I paid the same amount via debit card too. They said UPI will refund but even 12 days later too there is no refund and Google pay say the amount is successfully credited to CCD.
Help to refund my amount.
