BookMyShow — Payment deducted. But they didn't refund

I have tried to book a ticket on BookMyShow through big browser. The amount has been deducted from my account and it said the the ticket has been booked. I just go through the FAQ document and understood that the failed transaction amount will be refunded back to the customer. So I was waiting. But still it has not been refunded. When I created a ticket with BookMyShow [13129292], they told that they didn't get the amount and asked me to check the source.

When I checked the bank transaction, the amount has been deducted for the bookmy show. Please help me to get the refund from the bookmyshow site.
