My NBN upgrade? date was 19 March and as of today I have not had the final switch over done by Optus. NBN did everything they needed to do but the final set up of the modem connection was never completed and on the advice of the NBN tech who did the instal, my modem is not the correct one and should have been upgraded also. Since 19 March all I have achieved is a very long log of on-line chats (that service now turned off by Optus!) and now messaging on the Optus App which achieves nothing but referring you to quick help guides or phone numbers which never answer. When you do get to message with someone at Optus you have to start from scratch each time as they say they dont have time to go through your message log. It's an absolute debacle and a marketing case study in how not to outsource your business offshore and have zero client service capability in Australia where you claim to be a significant major telecoms player. Don't waste your time in a queue at an Optus Shop...the customer service? people there are just for selling mobile phone plans...one guy at the East Village Sydney shop told me he is totally non-technical and just back-filling a position as all their tech people have been taken out of the shops to support the network.
