Failure to install WIFI

Good day. I recently got myself a stable job and most of the time I have Teams Meeting with my bosses and we have a virtual school where we do courses that further help with sales. Because I am not always reachable telephonically I text my clients and managers so I decided go get fibre because I have heard good reviews about VUMA as I stay in Soweto and I’d be saving on data. I contacted them and they said before the proceed they need to see POP I paid at PnP and sent it to them. T was on the 25th of February on a Saturday. They said they would install in 14 days or less. They still have not installed and today is the 21/03. I am bitterly disappointed because in the duration that I have waited I have received little to no communication from them unless I touch base with them they don’t get back to me with the same urgency they promised. I have had three trainings and I attended those trainings on Microsoft Teams using my own data the very thing I was trying to avoid. They told me that it takes 7 attempts to call but no one has called me or my cousin who’s details I had enlisted and my desperation has resorted to Ke leaving my keys with my neighbour because I have to get to work. I am so frustrated because they won’t even reimburse me to go to RAIN or another company,they told me that they can’t install on Wednesday because they installers have a team building that they have to attend. I am beside beside myself and don’t know what to do. I need an installation or my money back.
