FTTH installation Quote

Let me start off by saying that I have been a very satisfied Vox Telecom customer, but this incident has really soured the g****s. This all started in November 2018, Openserve had completed the rollout of fibre infrastructure in my neighbourhood and I asked Vox Telecom for a quote to complete the last mile installation. I received the quote on the 22/11/2018 (quote # Q595650) , and I immediately accepted it as I believed it was a very good deal. A point to remember here is that the quote is valid until 19 Jan 2019. I received a number of emails from the Vox installation project team, setting the expectations with regards to project timelines. This all went quiet and I just assumed that it was because of the December holidays and people were on leave, etc. On Monday 7 Jan 2019, I rep**** to the last email I received (received on 27/11/2018) asking for an update on the progress. To my surprise I received an email from the salesperson with whom I had dealt with in November, he was informing me that they could not continue with the installation as Openserve had informed them that fibre is not available in my neighbourhood. I then sent Vox, screenshots taken from the Openserve website showing that in fact fibre is available in my neighbourhood - on Tuesday 08/01/2019, I received an email from Vox that Openserve had confirmed that fibre is available in the area, and I received a new quote from Vox (quote # Q626646) - the difference between quote # Q595650 and quote # Q626646 is that quote # Q626646 now included an installation fee of R1437.99. I queried the quote with the salesperson. My argument is that my acceptance of quote # Q595650 is still binding as Vox have yet to deliver on it, and if I had not accepted the quote in November, I could have accepted the quote at any stage up till 19 Jan 2019, and Vox would need to provide the installation at no cost to me. On Thursday 10 Jan 2019, the salesperson told me that his management had agreed to honour quote # Q595650, but final agreement had to come from the installation teams management. On Friday 11/01/2019, I sent the salesperson an email asking for an update and requesting the name of the person to whom I can speak to try and speed things up. I am still waiting for a reply to that email.

All I want is for Vox to agree to honour quote # Q595650, that I accepted in November 2018, and for them to expedite the fibre installation to my house.
