how do I delete 29,000 email numbers on my contacts list. most appear to bt tied up with the NSW education dept.
Optus were a waste of time
Are you using the OPtus web Email or a client on your PC?
You should be able to set up a POP account and import all the emails and delete them etc.
Perhaps try a free GMail account and import Optus emails (see settings options) then delete them all in one go.
Make sure the keep on server after downloading option isn't checked.
