Hello
Firstly Crowd Support is not an official customer service channel of Telstra.
We are mainly customers assisting other customers.
You will need to ring Telstra as you have before on 133 933 and speak with actual staff
The only Telstra staff here do moderation and do not have access to service as such
Before you do,
can you go through some of these tests please.

Have you tried using a network cable instead of wifi?
Thank you
