Mods wont be back until Monday to help. You could try live chat. To use live chat click talk to us at the bottom of this page then choose whether you're on bill or pre pay. It should pop up then. If Chrome browser acts up then try a different browser as some versions don't appear to play well with the links.
Please call 1907 (option 2) and get through to the Customer Options team.
They can issue your UAN.
