Bad Service and Communication - Vox Telecom

I've app**** for Fibre to be installed at my home in December 2019, completed all the application forms and submitted. Due to the December annual leave season it got postponed to Jan 2020 (what I can understand). 2nd week in January 2020, I followed up and the response was slow from Vox Telecom, after a few emails later an installation contractor was sent to my house to evaluate the installation. A few days later I had to follow up again and find out what is happening? I needed to submit the installation form (no communication on that part either), which I did and no further feedback was given back. I sent a email, requesting feedback and up to today (3 Feb 2020) I had no response.
