Mobikwik — Debited my bank account for voucher but didn't get it

I purchased amazon voucher used supercash and debit card. Supercash is 14.79rs and other balance is 485.21.
First i used this both of super cash and debit card but it failed. But in my bank account debited my cash. After i purchased after sometimes then same issue available.
So in my bank account 485.21+485.21rupees debited. I checked history invoice is not available, i saw its a pg transaction.
Please refund my money as soon as possible.
