HDFC Bank — UPI Transaction

Hi, on 16/12/2022, around 7 PM, I made a UPI transaction from my HDFC Bank app. The account number and IFSC code of the beneficiary's bank account was done correctly from my end. Then even though there wasn't any network issue, the transaction timed out and is now in pending state but the transaction amount i.e ₹3800 was debited from my HDFC account but not credited in the beneficiary's account still upto this time. I called the bank concerned customer care to enquire about the issue but the call always ended up before i can actually talk to the bank's customer care assistant. It now has been over 24 hours since the transaction was done, but the transaction amount still is neither credited to the beneficiary's account nor isn't refunded back to my HDFC account.

PLEASE HELP!
