BookMyShow — refund for unsuccessful transaction id [protected]

I am trying to get a refund for a failed transaction for past 20 days with no response from the bookmyshow support team. Every information with proof from the bank has been provided, but the things are delayed beyond expectations.
The ticket was booked on 19th may 2019. The request was raised the same day, but no resolution has been done to this date.
The worst part is there is no response from the support team. Even my email requesting me to provide an update as to whether i should wait or forget was never responded.
