Internet Reconnection

Level 2
I have just recently moved house and have not received an internet bill since living at my new/current address 
4 Trevellyan Street, Cronulla, 2230. 
I am furious as my internet has been turned off since 04/04/20. I have tried to call numerous of times during the week and have been hung up on every time I call. 
All I would like is to get my internet reconnected. It is essential for my internet to be connected during the COVID19 crisis because I am working from home. I need this issue sorted out ASAP.
