Live Chat not working

Level 1c

1. Your live chat is not working and you are all working remotely so we cannot call you. How are we supposed to contact you to resolve our issues? 

2. I called TPG to set up my internet on 23th February and I am still without internet. I need to work remotely because our offices are all closed. I have told TPG this and yet I still have no internet. I was told that I would be contacted about NBN coming to install my internet yet I have still not heard back. I contacted NBN directly and they said they could not help me and I needed to speak to TPG, but you are uncontactable(!?). I have had no other choice but to lodge a complaint with the TIO. Please can someone contact me to sort this out ASAP. It is absolutely ridiculous.
