user38878: I made a payment to somebody and now he is not replying me regarding the product I made the payment for and think its a fraud.
So I want to block the transaction.
All I have is the QR code of the person to whom the payment was made.
I also have the QR code detail

user37605: If the transaction has been confirmed there is nothing to do and that is probably your situation. If not (due a small fee) then you can pay yourself with a higher fee to "block" the previous one.
