PhonePe — Wrong transaction upi id

I have sent amount by mistake Rs.8873 to the upi id: [protected]@ybl instead of Rs.101. I dont know his account number or phone number. The upi id linked with phone pe. But i sent him through paytm platform with reference no.[protected]. Paytm was rejected my complaint and said go to bank and ask them. When i called to phone pe customer care they said they wont give any details of him. But, upi id linked with phone pe only.
