Refund not received after failed purchase

I purchased metro tickets through the Rapido application. During the payment process, the transaction showed as failed, but the money deducted from my account has not been refunded to me. I have sent three emails to Rapido's support email address ([protected]@rapido.bike) regarding this issue, but I have not received any response from them. I request that Rapido refund the amount deducted for the failed metro ticket transaction at the earliest.
