I've looked everywhere online and rang 150 I need to change my contact mobile number but there doesn't seem to be an option to do this need help
When calling in to 150, go with Option 1 -> Verify your account details when prompted for them -> From the main menu choose Option 4 -> Option 5. Do so between 8AM to 10PM M-Su. That'll get you through to Customer Relations. Ask them to update the contact phone number detail, they'll do it.
