Delhivery — Refund not received after a failed transaction

I made two transactions through GooglePay to Delhivery of Rs. 463 on 14th March 2023 at 05:54 pm and 05:56 pm respectively from my Delhivery account linked with phone number [protected]. Both of the transactions failed and I received a refund for only the first transaction which was done at 05:54 pm. It's been more than a week now and I have constantly tried to raise a ticket on the Delhivery app but there was no response. I even contacted GooglePay customer support and confirmed that the payment was done from their end to Delhivery.

I even tried contacting Delhivery Customer Support but none of their helplines were working.
