Hey. Its good to know I'm not the only one in this situation.
Not got it sorted yet. I've phoned the helpline twice.
The first time, I was told to phone 901, and press * then 4, and 1 or 2 for notification options, which is what we're looking for, but the option isnt given when I try it.
The second time, I was told to phone 1710. I've done this, but all it has done is turn on the Call Alert feature, which is supposed to text me everytime I have a missed call, and so far doesnt seem to work either, and its turned off voicemail (doesnt give a caller the chance to leave a message).
I have since went back to the voicemail options, with voicemail deactive and active, and still no option to do with notifications.
I might try the helpline again tomorrow. Dont think I can survive any more of their on-hold music for today.
Good luck finding an answer
