If you have sent the code to the wrong person, that person can still use the code. If you know the person, contact them and ask them not to use the code then send the code to the correct person. If you do not know the person, check if the code has been used. To do this, go to your nearest Pick n Pay or Boxer Kiosk and type in your ID Number and scan one of the fingerprints that you scanned when you registered. If it is still not collected, you can collect the money yourself and redo the transaction.
