HDFC Bank — UPI transaction dispute

Dear sir,
I was carrying out transaction of ₹1000 to Mr. Yashraj on 10 Apr 2023 which shown pending & later it got confirmed and the transaction was of ₹10000 erroneously. For which on same date i reported to HDFC Bank customer care as well as HDFC branch at Chadura, Budgam, J&K. But both of them denied to extend any kind of help. After registering the complaint, they disposed off without any clarification or resolution. I erroneously transferred the amount to Mr. Yashraj with UPI ID [protected]@paytm having contact number : +[protected] but he is not responding
